1 Introduction

Overview

The CETAC ASX-112FR autosampler is designed to be sturdy, reliable, and easy to use. It provides automated sample introduction that enables you to perform other tasks while the autosampler runs. The ASX-112FR autosampler automatically introduces up to 96 samples when fully loaded. It contains a microprocessor that allows sequential or random sampling, providing flexibility.

The autosampler is typically interfaced to and controlled by the ICP-MS instrument host computer using a serial or USB connection.

The ASX-112FR offers a small footprint to conserve bench space, a short sample path to preserve valuable sample, and a protective cover to prevent sample contamination. The dual flowing rinse station prevents carry over to ensure sample integrity. The ASX-112FR is both contamination and corrosion resistant and offers a completely inert flow path.

The ASX-112FR can be conveniently placed on top of the CETAC Aridus II™ or Aridus3 Desolvating Nebulizer System. The Aridus is commonly used for signal enhancement/interference reduction for ICP-MS. Applications include corrosive, limited-volume samples for geology and semiconductors.

About This Book

This document describes the procedures for installing, using, and maintaining the autosampler. It also provides information about troubleshooting minor problems and describes the design of the autosampler.

This manual covers the following products:

 CETAC ASX-112FR

Who Should Read This Book

The primary audience for this manual consists of analytical chemists and lab technicians. To use this manual effectively, you should have a basic knowledge

ASX-112FR Autosampler Operator’s Manual

Chapter 1: Introduction

of chemistry, a basic knowledge of electronic sampling equipment, at least a beginning level of computer experience, and working knowledge of the analytical instrument used with the autosampler.

WARNING

CHEMICAL INJURY HAZARD The autosampler is intended for use only by qualified operators who have been trained in safe laboratory practices. Make sure you know the hazards associated with all of the chemicals you are using, and take the appropriate precautions. Exposure to laboratory chemicals may result in serious injury.

Autosampler Configuration Options

The ASX-112FR is very configurable making it ideal for use in multiple applications. Three models are available. The standard model comes with a polypropylene rinse station controlled by a peristaltic pump. A second model comes with a polypropylene rinse station controlled by a gas displacement pump, which uses compressed gas to push the rinse solutions through the rinse station. A third model is equipped with a PFA rinse station and a gas displacement pump for ultra-clean applications.

All three models have the option to be selected in either a tall or short configuration. The height configuration restricts the choice of racks to be either tall—BelArt half racks (with 7 mL or 14 mL vials) or short—CETAC racks for small samples (with 0.5 mL, 1.0 mL, 1.5 mL or 2 mL vials). The rinse station is also configured in either a tall or short version.

Three probe sizes are offered: 0.010” (0.25 mm), 0.010” (0.25 mm) ID, and

0.035” (0.89 mm) ID. The 0.035” ID is expected to be the standard with the

0.010” ID designed for a low-flow (<0.5 mL/min) nebulizer. If the ASX-112FR is used with the CETAC Aridus II™ or Aridus3 system, then the uptake line of the C-Flow PFA n ebulizer is typically used as the sample probe in a selfaspiration mode.

Spares kits are available to convert a tall model into a short model, and vice versa. Optional rack kits are also available as spares.

The front of the ASX-112FR is shown in Figure 1-1.

2 Preparing for

Installation

Installing the autosampler requires preparation. Before you install the autosampler, you should evaluate the physical arrangement of the laboratory to choose a suitable location. Once you choose a location, you must carefully unpack the autosampler prior to beginning the installation.

This chapter discusses what requirements must be met when you choose a location. It also describes how to unpack the equipment before installation.

Choosing a Location

Choosing a location for the autosampler involves evaluating the lab environment for the availability of space, liquid waste routing an d po wer. For the system to function optimally, the location you select must meet specific requirements associated with each of these items. The following sections discuss space, water, and power requirements.

Space Requirements

Most analytical applications benefit from utilizing the shortest sample flow path. Therefore, you should place the autosampler in close proximity to the analytical instrument. The recommended footprint for the autosampler is shown in the following table.

Dimensions Recommended Footprint

Height 44 cm (17.3") 55 cm (22")

Width 34 cm (13.4") 44 cm (17")

Depth 52 cm (20.5") 59 cm (23")

Weight 14.1 kg (31 lbs)

Table 1: Physical Characteristics – ASX-112FR

The weight shown is that of the autosampler itself, without the desktop power supply or other accessories.

ASX-112FR Autosampler Operator’s Manual

Chapter 2: Preparing for Installation

Allow at least 5 cm behind the autosampler for power cord and communication cable egress. Always position the equipment so that it is easy to disconnect the power cord.

Work Surface Requirements

The ASX-112FR can be conveniently placed on top of the CETAC Aridus II or Aridus3 Desolvating Nebulizer System. Otherwise, the autosampler must be placed on a sturdy countertop or table. Do not place the autosampler on a wheeled cart or folding table.

During operation, the autosampler produces both vertical and horizontal forces. If the work surface is allowed to shake or wobble, the autosampler may “walk” across the surface, liquids may spill, or data quality may be affected.

Rinse Solution Requirements

For most applications, 2% nitric acid (HNO3) (v/v) is used as the primary rinse agent and deionized water is used as the pre-rinse agent in the ASX-112FR. Place the rinse agent source(s) within two meters of the ASX-112FR.

WARNING

CAUT ION

CHEMICAL INHALATION AND BURN HAZARD Observe all necessary safety precautions when handling nitric acid (HNO3) solutions. Wear appropriate personal protective equipment, including face shield or goggles, gloves, and a laboratory coat, and ensure that engineering controls (such as ventilation systems) are operating properly.

Liquid Waste Routing Requirements

Ensure that there is a liquid waste receptacle within two meters of the autosampler. The waste receptacle inlet should be 30 to 60 centimeters lower than the tubing drops directly into the waste receptacle with no coiling and without being submerged below the liquid level of the waste receptacle.

SUBMERGED DRAIN TUBING MAY CAUSE EQUIPMENT DAMAGE

Ensure that the rinse drain tubing is not submerged in the waste liquid. If the tubing is submerged, waste liquid can back up in the rinse station, flooding the sample tray and potentially damaging the electronics.

conductors and ground. A protective ground connection by way of the grounding connector in the power cord is required for safe operation.

Ensure that you position the autosampler so that the location where the power supply cord plugs into it is easily accessible (is not blocked) and it can be quickly disconnected if needed. In case of hazard, the autosampler should be disconnected from the power source.

The power supply socket is on the back of the autosampler (see Figure 1-4 on page 11). Connect the power supply to the autosampler first and then connect a line cord to the power supply. Do not apply power to the power supply until ready to operate the autosampler.

Unpacking the Autosampler

WARNING

CAUT ION

LIFTING HAZARD The autosampler may be awkward to lift. Incorrect lifting technique may cause personal injury. Use caution when lifting the autosampler.

Inspect external packaging upon receipt for signs of shipping damage. Inspect all items during unpacking and notify the carrier immediately of any concealed damage. Check for any kinked or bent tubing.

If the system is shipped or removed from storage during cold weather, allow the packaged equipment to equilibrate to room temperature before opening and exposing to warm, humid air. It is usually sufficient to provide four to eight hours for this purpose.

EQUIPMENT DAMAGE FROM CONDENSATION

If condensation forms on or inside the autosampler, allow it to dry thoroughly before connecting it to a power source and operating it. Failure to do so may cause equipment damage.

Remove the packing checklist from the shipping container, and check off items against it. Leave accessories in the packing until you are ready to install them.

NOTE

Keep the factory packaging for use in case the product ever needs to be returned or shipped to another location.

Figure 3-2. Sample Probe Assembly Installation.

Figure 3-2 illustrates the sample probe assembly installation. The instructions below can be used for the standard probe or the uptake capillary of the C-Flow PFA nebulizer.

1 Insert the probe through the cylindrical support collar.

2 Using just your fingers, tighten the thumbscrew on the side of the collar to

secure the probe in the collar.

3 Insert the probe into the Y-arm assembly.

NOTE

The Y-arm assembly has two holes at either end. Use the smaller hole if you are using the C-Flow PFA nebulizer; reverse the Y-arm assembly to use the larger hole if you are using the standard probe.

NOTE

The support collar simply rests on top of the end of the Y-arm assembly. If the end of the probe hits the edge of a sample vial or a solid part of the rinse station block, the probe and collar will be pushed upward without bending (and possibly damaging) the probe.

4 Loosen the thumbscrew on the collar and set the probe a little higher than

where you think it needs to be. Later on, after the probe height has been checked, you can lower the probe.

The cabinet-mounted rinse station is located at the left-front side of the autosampler within the cover. The ASX-112FR provides the ability to use two separate rinse solutions in a dual flowing rinse station as shown in Figure 3-5. Typically, deionized water is used as a pre-rinse solution and an acid solution, such as 2% HNO solutions may be pumped into the rinse station by either an on-board peristaltic pump or with a gas displacement pump.

is used as the primary rinse solution. The dual flowing rinse

ASX-112FR Autosampler Operator’s Manual

Chapter 3: Installing the Autosampler

Figure 3-5. Dual Flowing Rinse Station.

The rinse solutions are pumped into the rinse station through two ports at the bottom of the rinse station and are drained from the top of the rinse station. This up-flow rinsing is the most effective method for decontaminating the sample probe between samples.

The waste rinse solutions drain from the top of the rinse station by gravity; it is therefore necessary to ensure the drain tube hangs straight and is unhindered in its path to the waste container.

Peristaltic Pump Configuration

In the gravity drain arrangement, the rinse solution moves through both channels of the peristaltic pump to the dual inlets at the bottom of the rinse station. It then drains out a single gravity drain at the top of the rinse station. The rinse speed of the peristaltic pump is configurable through ICP-MS command or through the provided pump speed utility (see page 52). Smaller diameter pump tubing is available to enable lower rinse solution flow rates.

This tubing (Tygon

) is available in spare part kit SP7296.

To connect the rinse station tubing to the rinse station, complete the following steps:

1 Remove the two thumbscrews that secure the rinse station and then remove

the rinse station from the autosampler by gently pulling it away from the support guide posts.

To connect the rinse station tubing to the gas displacement pump using a gravity drain, complete the following steps with reference to Figure 3-7 and Figure 3-8:

1 Two PFA bottles are provided for the rinse solutions. After filling each bottle

with the appropriate rinse solution, ensure that the caps for each bottle are secure. A dedicated wrench (green color) is provided to tighten the caps. Label the bottles #1 and #2; fill bottle #1 with pre-rinse solution (ex. deionized water) and bottle #2 with full rinse solution (ex. 2% nitric acid).

2 Rinse Bottle to Rinse In Ports – Use two lengths of approximately 48 inches

(1.2 meters) each of 1/8 inch O.D. x 1/16 inch I.D. PTFE tubing. Attach one end of each length of tubing into the two “RINSE IN” ports on the gas displacement pump panel. Use the fittings and ferrules provided. Place the other end of each length of tubing into a fitting on the top of the cap of each PFA bottle. The tubing should extend through the fitting and into the rinse solution. If the tubing will not go through the fitting, then try the other fitting. “RINSE 1 IN” should be connected to bottle#1 with the pre-rinse solution and “RINSE 2 IN” should be connected to bottle#2 with the full rinse solution. Ensure that each fitting is tight.

3 Argon Out to Rinse Bottle – Use two lengths of approximately 48 inches (1.2

meters) each of 1/8 inch O.D. x 1/16 inch I.D. PTFE tubing. Note that this tubing will have pressure relief valves already attached. Attach one end of each length of tubing into the two “Argon Out” ports on the gas displacement pump panel. Use the fittings and ferrules provided. Place the other end of each length of tubing into the other fitting on the top of the cap of each PFA bottle. Note that the tubing should only extend to the bottom of the fitting and not below the level of the liquid in the bottle. The “ARGON OUT” connection below the “RINSE 1 IN” port should be connected to bottle#1 with the pre-rinse solution. The “ARGON OUT” connection below the “RINSE 2 IN” should be

WARNING

Never attempt to load, unload or reposition the sample vial rack or sample vials while the autosampler is operating. The sample probe may move unexpectedly and cause an injury.

Figure 3-11. ASX-112FR Autosampler Rotary Tray

The ASX-112FR features a rotary tray, shown in Figure 3-11, which holds both standards and samples. A variety of sample racks can be placed within the center cavity of the rotary tray. Sample racks are classified as short or tall, allowing the ASX-112FR to be configured in either a short or tall configuration. Standards vials also vary between the short and tall configurations. For the short configuration, standard positions 1 through 5 hold 20 mL vials and standard positions 6 through 14 hold 4 mL vials. For the tall configuration, standard positions 1 through 5 hold 30 mL vials and standard positions 6 through 14 hold 10 mL vials.

Short Rack Configuration

Figure 3-12. CETAC Sample Racks – Short Rack.

ASX-112FR Autosamplers Operator’s Manual

Chapter 3: Installing the Autosampler

Three CETAC sample racks are available for the short configuration. These are shown in Figure 3-12.

To assemble and place the samples and standards for a short configuration, complete the following steps:

1 Ensure the short sample tray adapter plate is screwed into place in the center

of the rotary tray. It should be placed so that the alignment guide is placed nearest the guide dot as shown in Figure 3-11. An ASX-112FR ordered in a short configuration will be shipped with the adapter plate in place.

2 Place the standards vials in the rotary tray as shown in Figure 3-11.

3 Load the sample vials in the sample tray and place the tray in the center of the

rotary tray aligning the groove on the bottom of the tray with the alignment guide on the adapter plate. This should also align the two alignment dots on the corner of the sample tray and the rotary tray.

A correctly placed sample vial rack will not move more than ± 0.2 millimeters unless lifted. A tilted sample vial rack or vials indicate an improperly placed rack or vials, which must be corrected before you operate the autosampler.

4 Replace the autosampler cover by sliding it into the groove in the rinse

alignment block.

The cover on the ASX-112FR has a hinged front door, secured by a bar latch, which can be opened to add or remove sample vials or the sample vial rack. The entire cover itself can also be fully removed. Avoid removing the cover during operation; this could result in an impact to the Y-arm assembly causing an alignment error. In the case of a mechanically induced alignment error, the power to the unit would need to be cycled off and on to realign the Y-arm.

Tall Rack Configuration

Chapter 3: Installing the Autosampler

Connecting the Autosampler to an Analytical Instrument

You can connect the autosampler directly to a sample introduction peristaltic pump and then to the ICP-MS or to a sample introduction device, such as the CETAC Aridus II or Aridus3 Desolvating Nebulizer System. To do so, complete the following steps:

1 Determine the free length of the sample probe tubing you need, add 10

centimeters, and cut the free end of the sample probe to length.

Determining the free length includes allowance for movement of the Y-arm in the X, Y, and Z axes. The additional 10 centimeters provides a service loop for unrestricted sample probe motion.

Excessively shortened sample probe tubing is not repairable and must be replaced.

2 Connect the free end of the sample transfer tubing to the inlet of the analytical

instrument’s peristaltic pump tubing.

The free end may be connected directly to the ICP-MS nebulizer. If the CETAC C-Flow PFA nebulizer is used (the free end acting as the sample probe for the ASX-112FR) then the nebulizer may be installed directly into the Aridus II or Aridus3 PFA spray chamber or the host ICP-MS spray chamber.

Connect the ASX-112FR Autosampler to the Host Computer

Instrument control software on the ICP-MS host computer controls both the analytical instrument and the autosampler. You cannot operate the autosampler until you establish a communications interface between the autosampler and the host computer. It is through this interface that the host computer directs the operation of the autosampler. The autosampler supports the following communications protocols:

 The serial (RS-232) protocol is the standard configuration. There are two

RS-232 serial ports on the autosampler, and a serial interface kit is shipped with the autosampler.

 The parallel (IEEE-488) protocol is less common than the serial

configuration. An IEEE-488 interface kit is available as an optional accessory to the ASX-112FR.

 The USB interface is an optional configuration. A virtual COM port is

created when using the USB and therefore, the connection looks like a standard RS-232 serial port to the host PC software.

NOTE:

Although the autosampler supports several communications protocols, the host computer governs which protocol is used. To determine which protocol is

ASX-112FR Autosamplers Operator’s Manual

Chapter 3: Installing the Autosampler

required for the analytical instrument you are using, refer to the hardware or software manual provided with the ICP-MS instrument.

Establishing an RS-232 Serial Communications Interface

The serial interface kit provided with the ASX-112FR Autosampler includes an interface cable equipped with two modular port adapters. Use the interface kit to establish a serial communications interface with the host computer. To do so, complete the following steps:

1 Plug one end of the cable into the host computer’s serial (COM) port selected

for autosampler communications.

Make sure that the COM port you select matches the port selected in the host computer’s software.

2 Finger tighten both screws of the cable adapter.

CAUT ION

NOTES

If a host computer serial port with a DB9F, a DB25M, or a DB25F connector (9 pin D-submini receptacle or 25 pin D-submini plug or receptacle) must be used, use the mating connector from the Teledyne CETAC Technologies universal port adapter kit. You can order the adapter kit from Teledyne CETAC Technologies or purchase an adapter locally to convert the serial port to a DB9M. Do not use a

“null modem” adapter.

Ensure you are connecting the serial cable to the COM1 port. Connecting the adapter to the Dilutor (COM2) port on the autosampler will cause a malfunction.

When interconnecting any computing devices, keep the communications cables away from sources of electromagnetic or radio frequency (RF) interference, such as electric motors, transformers, fluorescent light ballasts, or RF energy sources. Limit cable runs for RS-232C to less than 16 meters. If these conditions cannot be satisfied, use low-impedance, fully shielded cables to provide satisfactory operation. The cables are available from many sources, but you will need to specify the correct mating connectors and “straight-through” (DTEDCE) wiring.

3 Connect the other end of the cable to the ASX-112FR COM1 port.

Ensure that you are connecting the adapter to the COM1 port. Connecting the adapter to the AUX I/O port on the autosampler will cause a malfunction. The autosampler AUX I/O port is used for communications to a device other than the host computer.

4 Finger tighten both screws of the cable adapter.

Chapter 3: Installing the Autosampler

Establishing a USB Communications Interface

If the host computer does not have an available RS-232 port, you can use a USB port instead. An “A-B” USB cable may be obtained from any computer store.

The procedure for finding and installing the USB driver may be different, depending on your computer's operating system.

1 Power up both the computer and the autosampler.

2 Plug one end of the cable into the host computer's USB port and the other end

to the autosampler’s USB port.

The computer screen should display a "New Hardware Found" window. A USB driver must be installed to make the USB port emulate an RS-232 COM port, and the installation must be repeated for each USB connection.

The exact procedure for installing the driver depends on the version of the host computer’s operating system. The instructions which follow show installation on the Windows XP operating system.

3 Allow the Windows Found New Hardware Wizard to use Windows Update to

search for a driver.

In most cases, the driver will be found online and installed automatically. This process may take several minutes.

ASX-112FR Tray Files

Before the ICP-MS can work with the ASX-112FR, the tray files may need to be loaded in the proper ICP-MS software program location. The tray files are provided on the CETAC Installation CD along with ICP-MS specific instructions for loading the files.

4 Verifying Installation

Once installation of the autosampler is complete, it is important to verify that you have installed it correctly. Attempting to use it before ensuring that it is installed correctly may result in damage to the autosampler.

Verifying installation of the autosampler consists of two parts:

 Ensuring that the communications interface between it and the host

computer is working.

 Ensuring that the sample probe functions properly.

This chapter explains how to test the above items before using the autosampler.

NOTE:

The procedures given in this chapter are for use in a Windows XP environment.

Testing the Communications Interface

If the communications interface between the autosampler and the host computer is not established correctly, the autosampler will not function.

1 Check that the communication cables are properly attached between the host

computer and the autosampler.

2 Turn on power to the autosampler.

3 Connect to the autosampler using the host ICP-MS software or a terminal

emulator program such as C-Ter m .

See “Operating a CETAC Autosampler Using a Terminal Program” on page 69 then continue with step 4.

4 Enter the HOME command.

The autosampler should reset, with the Y-arm moving out and back into the home position and the rotary tray moving out and back into home position. If the autosampler does not reset, see “Troubleshooting the Autosampler” on page 63.

ASX-112FR Autosampler Operator’s Manual

Chapter 4: Verifying Installation

5 Enter the RINSE command.

The Y-arm should dip first into the center of the pre-rinse location and then into the center of the full rinse location.

NOTE:

The autosampler Y-arm and probe can usually be sent to the HOME and RINSE positions by clicking a button in the host ICP-MS software.

Checking the Autosampler Components

The following autosampler components may be damaged during shipping or installation: the sample probe, the peristaltic pump tubing, and the rinse station and tubing. It is important that you check these components for damage before you operate the autosampler. To do so, complete the following steps:

1 Shut down and unplug the autosampler.

2 Visually inspect the sample probe, peristaltic pump tubing, and rinse station

and tubing for leaks or signs of damage.

3 If using the gas displacement pump with PFA bottles, ensure that the bottles

are sealed tightly.

If you detect a leak or other damage to an autosampler component, you must replace it. For more information, see the appropriate section in Chapter 6, “Maintaining the Autosampler.”

4 Install the sample probe in the Y-arm assembly as directed in Chapter 3,

“Installing the Autosampler.”

Testing the Sample Probe

The sample probe must descend into the center of each sample vial to ensure satisfactory sample uptake. Shipping or rough handling can disturb the autosampler’s cabinet-to-base alignment. If it is incorrectly aligned, the sample probe will not function properly. It is therefore important to test the sample probe before you actually run samples with the autosampler.

NOTE:

Before testing the sample probe, ensure that you have installed all autosampler components correctly. Also, ensure that you have securely tightened all thumbscrews and connected the communications cable from the host computer to the autosampler.

Testing the sample probe involves observing the operation of the sample probe. To do so, complete the following steps:

ASX-112FR Autosamplers Operator’s Manual

Chapter 4: Verifying Installation

1 Load the autosampler sample tray with an empty sample rack.

If multiple sample vial racks (different numbers of positions) will be used, select the sample rack containing the maximum number of positions for the initial verification run.

For information about placing the sample rack, see Chapter 3, “Installing the Autosampler.”

2 Turn the autosampler power switch on and verify that the LED power

indicator is on.

The LED power indicator is green in color. The indicator will flash upon power up and will then remain lit when the unit is at the ready state. It is located on the front of the unit at the top right corner of the base, directly above the power switch.

3 Using the ICP-MS software, designate the sample positions at the left rear, left

front, right rear, and right front of the sample tray.

Figure 4-1. Sample Test Positions.

4 Place sample vials at the four corners.

5 Command the autosampler to move the sample probe to the designated

sample positions. Check that the sample probe correctly accesses each position and that the probe descends into the center of each sample vial.

NOTE:

If the autosampler alignment is not correct, contact Teledyne CETAC Technologies Customer Service and Support or an authorized representative.

5 Using the Autosampler

Before using the autosampler, ensure that your lab environment provides operating conditions that will prolong the life of the autosampler. Once the proper operating conditions are met, you can arrange the sample vial racks and start the autosampler sequence run. When you finish using the autosampler, you may need to flush the rinse station and flow path before shutting the autosampler down.

Establishing Optimal Operating Conditions

The autosampler operates reliably even under less than ideal conditions. It is not, however, indestructible. Malfunction or damage can occur if specific operating conditions are not met. Meeting these conditions requires that you create the proper lab environment, replace autosampler components that wear out under normal use, and purchase the appropriate supplies for use with the autosampler. The following sections explain how to meet these conditions.

NOTE

Damage or malfunction that results from unsatisfactory operating conditions may constitute misuse and abuse and be excluded from warranty coverage.

Creating the Lab Environment

To create satisfactory operating conditions in your lab environment, follow these guidelines:

 Operate the autosampler in a conventional lab environment where the

temperature is 55–85 °F (13–30 °C), the humidity is 0–60% non-condensing, and the unit is not exposed to excessive flammable or corrosive materials. (See also "Environmental Characteristics" on page 77.)

 Avoid rough handling of the autosampler. If possible, do not expose the

autosampler to vibration or shock.

 Protect the autosampler from long-term exposure to condensation,

corrosive materials, solvent vapor, continual standing liquids, or large spills into the autosampler cabinet or arm. Exposures of this type can damage the drive mechanisms as well as the electronics.

ASX-112FR Autosampler Operator’s Manual

Chapter 5: Using the Autosampler

 Observe the same general electrostatic discharge precautions as with any

other integrated circuit electronic devices. Low humidity environments, especially when combined with static-generating materials, require maximum care.

CAUT ION

Discharge static buildup and ground to the autosampler base or cabinet before performing any maintenance. Do not touch or short-circuit bare contacts, COM1, DILUTOR, or auxiliary ports.

 Avoid using the autosampler if strong electromagnetic interference, radio

frequency interference, or radioactivity is present. Interference fields can cause erratic operation of the autosampler. The autosampler will not function properly if the level of radioactivity is above background.

Replacing Auto Sampler Components

The following components wear out under normal use and must be replaced periodically:

 Peristaltic pump tubing

 Rinse tubing

 Sample probe

If you fail to replace these components when they deteriorate, the autosampler will not function properly. For information about replacing autosampler components, see Chapter 6, “Maintaining the Autosampler.”

Purchasing Supplies

Because the life-span of the sample and standards vials varies, you should maintain an adequate supply of spare vials. When you need to purchase additional supplies, it is extremely important that you choose the appropriate sizes and materials.

When you purchase sample and/or standards vials, make sure they meet the following requirements:

 The diameter of the sample or standards vial matches the rack size you are

using.

 The height of the vials matches the height configuration of the unit. Be sure

the Y-arm height setting, the sample rack, and standards are all short or all tall.

 The material selected is compatible with the samples, standards and your

analytical requirements. Ultra-high purity, ultra-trace applications are facilitated with Polytetrafluoroethylene (PTFE), Fluorinated Ethylene Propylene (FEP), Perfluoralkoxy (PFA) or similar materials.

ASX-112FR Autosamplers Operator’s Manual

Chapter 5: Using the Autosampler

CAUT ION

Use of mismatched sample vials and sample vial racks may result in malfunctions or sample spills. Be sure your vials meet the given requirements.

To order additional supplies, refer to the CETAC Accessories and Supplies Catalog for the autosampler, available on the CD or on the CETAC Web site,

www.cetac.com.

Arranging the Sample Vial Racks

You can change the arrangement of the sample vial racks to meet your needs. The ASX-112FR autosampler accommodates one sample rack.

For more information about placing sample vial racks in the sample tray, see Chapter 3, “Installing the Autosampler.”

Define the number of sample positions for a sample rack through the host instrument software.

Incorrectly defining the position count in the ICP-MS software can result in sample spills and invalid analysis results.

Starting the Autosampler

WARNING

Once you arrange the sample vials and ensure that the arrangement is correctly defined in the software, you can start the autosampler and let it run until the sampling sequence is finished.

PINCH HAZARD Keep fingers, hair, and loose clothing away from the moving parts of the autosampler.

CHEMICAL BURN HAZARD Make sure that all tubing is securely connected and that all protective covers are in place before operating the autosampler. Use proper laboratory practices and appropriate personal protective equipment.

1 Ensure that the rinse station is properly connected.

2 Turn the autosampler power switch on.

The LED power indicator on the autosampler lights up when the power is on.

3 Turn on the peristaltic pump using the host ICP-MS software or through

C-Term.

4 Adjust the peristaltic pump shoe until the desired rinse solution flow rate is

achieved.

5 Purge air from the rinse system by running the rinse solutions through the

rinse station.

ASX-112FR Autosampler Operator’s Manual

Chapter 5: Using the Autosampler

Ensure there are no air bubbles visible in the rinse uptake tubing before you run samples with the autosampler.

6 Access the host computer’s ICP-MS software and activate the autosampler

program.

Define and start the sampling sequence. The autosampler runs until it reaches the end of the sampling sequence.

Shutting Down the Autosampler

To shut down the autosampler, complete the following steps:

1 (Gas-Displacement pump equipped models) Drain the rinse system by removing

the rinse solution uptake tubing from the rinse solution source. Let the gas displacement pump run until all solution drains from the tube attached to the rinse station outlet.

If you use a rinse solution other than deionized water, flush the rinse system with deionized water before shutting down the autosampler. For more information, see “Flushing the Rinse Station and Flow Path” on page 50.

2 Turn off the autosampler power switch.

3 If you will be performing maintenance, unplug the power cord either at the

power supply or at the wall outlet.

4 (Peristaltic pump-equipped models) After the rinse station has been pumped

empty and the power turned off, place the uptake tubing into a clean waste container. Release the peristaltic pump pressure shoes from contact with the pump tubing by disengaging their latches, allowing any remaining rinse solution that may be trapped in the rinse system to drain to the waste container. (Be sure to re-engage the pressure shoe latches and return the rinse solution uptake and drain tubing to the proper vessel(s) before restarting and operating the autosampler.) Releasing the pressure shoe decreases wear on the pump tubing.

Flushing the Rinse Station and Flow Path

Generally, you can operate the autosampler without flushing the rinse system. Under normal circumstances, you can simply drain the rinse system prior to shutting down the autosampler. However, you need to flush the rinse station and flow path under two circumstances:

 During initial startup of the autosampler after installation.

 After the use of more concentrated (>10% (v/v)) bases, acids, or organic

solvents as rinse agents.

Flushing the rinse system during initial startup of the autosampler removes any contaminants that could cause interference during sample analysis. Flushing the rinse system after using stronger rinse agents prevents degradation and failure of the flow path components.

ASX-112FR Autosamplers Operator’s Manual

Chapter 5: Using the Autosampler

To flush the rinse station and flow path, complete the following steps:

1 Insert the rinse uptake tubing into a deionized water source.

NOTE

If you are flushing the rinse system during initial startup, first use a 2% nitric acid solution as the rinse agent, followed by deionized water.

2 Run the rinse solution through the rinse station and flow path for 5 to 10

minutes.

Once you flush the rinse system, you can proceed with the sampling sequence or drain the rinse system as part of the shutdown procedure.

Reconfiguring the Autosampler Sample Height

The autosampler may be reconfigured from a short configuration to a tall configuration or vice versa.

To change the height configuration of the ASX-112FR autosampler, complete the following steps:

1 Turn off power to the autosampler and unplug the power cord.

2 Open the larger of the two access panels on the bottom of the autosampler to

reveal the eight-position dip switch.

3 Adjust the position of dip switch number six to match the intended height

configuration:

 Tall: Switch 6 = 1

 Short:Switch 6 = 0

4 Change the rinse station from short to tall or vice versa.

The ASX-112FR comes with a single rinse station, either a tall or short version. However, a secondary rinse station may be purchased if the customer has a need to run in both tall and short configurations.

Follow the steps for “Replacing the Rinse Station” on page 58.

5 Move the Y-arm from the short position to the tall position or vice versa.

Remove the thumbscrew and reposition the Y-arm in the desired location (see "Figure 3-1. Y-Arm Mounting Positions." on page 20). Replace the thumbscrew.

6 Place the new set of standards and vials in the autosampler tray, along with the

sample rack. Remember than an adapter plate is required for a short rack.

7 Loosen the thumbscrew on the side of the collar to make fine adjustments to

the height of the probe.

1 Shut down and unplug the autosampler power cord.

2 Remove the cover.

3 Remove all sample and standard vials and the sample rack.

4 Restore power to the autosampler.

5 Ensure that the rinse system is fully drained to prevent any solution spills that

may be hazardous to personnel or may damage electronic components (see “Shutting Down the Autosampler” on page 50).

a. (Peristaltic pump-equipped models)

i. Drain the rinse system by removing the rinse solution uptake

tubing from the rinse solution source. Allow the pump system to run until all solution drains from the tube attached to the rinse station outlet.

ii. After the rinse station has been pumped empty and the power

turned off, place the uptake tubing into a clean waste contain e r. Release the peristaltic pump pressure shoes from contact with the pump tubing by disengaging their latches, allowing any remaining rinse solution that may be trapped in the rinse system to drain to the waste containers. (Be sure to re-engage the pressure shoe latches and return the rinse solution uptake and drain tubing to

ASX-112FR Autosamplers Operator’s Manual

Chapter 6: Maintaining the Autosampler

the proper vessel(s) before restarting and operating the autosampler.)

b. (Gas displacement pump-equipped models)

i. Drain the rinse system by raising the rinse solution uptake tubing

to a position that is above the liquid level in each rinse vessel (Use caution to ensure that each rinse solution vessel is not pressurized while performing this operation). Reapply gas pressure to each vessel. Allow the pump system to run until all solution drains from tubing attached to the rinse station outlet.

ii. After the rinse station has been pumped empty, and while the

rinse pump function is still operating, shut off the gas supply to the autosampler. Allow the rinse system to depressurize as it operates. This will allow the system to be fully evacuated. (Be sure to return the rinse uptake tubing to its proper position below the rinse solution vessel liquid level, ensure that drain tubing is properly placed/positioned, and to restore gas supply pressure to the system before restarting and operating the autosampler.)

NOTE:

If using rinse solution other than deionized water, flush the rinse system with deionized water prior to removing the rinse station. For more information, see “Flushing the Rinse Station and Flow Path” on page 50.

NOTE:

Prior to removing the rinse station, it is important to safely and fully drain/evacuate the entire rinse system. See “Replacing the Rinse Station” on page 58, and “Flushing the Rinse Station and Flow Path” on page 50. Doing so prevents rinse solutions from coming into contact with personnel, and also from damaging any autosampler components (electronic or otherwise) not intended for such exposure.

Replacing Peristaltic Pump Tubing

On units with a peristaltic pump, routine maintenance of the autosampler includes replacement of the peristaltic pump tubing. Because of the operating nature of peristaltic pumps, the tubing will probably be the most frequently replaced item on the autosampler. If you use more concentrated (>10% (v/v)) bases, acids, or organic solvents as rinsing agents, the tubing may degrade more ra pidly.

WARNING

To replace the peristaltic pump tubing, complete the following steps:

PINCH HAZARD Turn off power before servicing the peristaltic pump or pump tubing.

1 Pump deionized water through the pump tubing to remove any acid rinse

solution.

2 Shut down and unplug the autosampler power cord.

3 Release the pressure shoe and remove the old tubing from the barbed fittings.

Drain any remaining rinse solution (see the instructions in "Replacing the Rinse Station" on page 58).

Carefully pull or cut the old tubing to remove it.

4 Replace the pump tubing by pushing the new tubing onto the fittings.

Install the new tubing carefully. Damage can result if you apply too much force.

5 Reconnect the pressure shoe.

ASX-112FR Autosamplers Operator’s Manual

 The diameter of the sample or standards vial matches the rack size you are

using.

 The vials are not too tall.

 The material is compatible with the samples or reference standards.

CAUT ION

Always use the correct vials. Use of mismatched sample vials may result in malfunctions or sample spills. See page 8 for supported vial sizes.

7 Troubleshooting the

Autosampler

When the autosampler does not function properly, isolate the problem to determine if it originates in the host computer, the analytical instrument, the RS-232 cable, USB cable or the autosampler. If you determine the problem is in the ASX-112FR, check the power system, the communications interface, or the sample probe assembly to find the cause of the problem and resolve it.

This chapter explains how to troubleshoot autosampler problems. If you cannot solve a problem using the steps given in this chapter, you should contact Teledyne CETAC Technologies Customer Service and Support.

Power System Problems

A possible cause of system malfunction is a problem in the power system. If the system is not functional, it is possible that it is not receiving power. If this is the case, the LED status indicator light will be off. To troubleshoot this problem, complete the following steps in sequence until the problem is solved:

1 Check that the power switch on the autosampler is turned on.

2 Check that the power cord is plugged in firmly between the power input on the

autosampler and the external power supply and also between the power supply and the wall outlet.

If the cable is plugged in, ensure that it is not damaged in any way.

3 Check that the LED on the power supply is illuminated.

If the LED is not illuminated, check the wall outlet using a device approved for that purpose.

If the wall outlet is working and the voltage is acceptable, unplug the external power supply from the autosampler, but leave it plugged into the wall.

 If the LED is not lit, the power supply is faulty and requires replacement.

ASX-112FR Autosampler Operator’s Manual

Chapter 7: Troubleshooting the Autosampler

 If the LED is lit when unplugged from the autosampler but turns off when

plugged into the autosampler, the autosampler may have an internal short and requires repair.

4 Check the wall outlet.

The power supply may trip a GFI (ground fault interrupt) outlet in its normal operation as it discharges internal capacitors. Make certain that the power supply/cooler unit is not plugged into a GFI outlet. If it is, move the AC line cord to a standard outlet, or have a qualified electrician switch the AC power outlet from GFI to a standard, grounded outlet.

5 If the external power supply LED is illuminated while plugged into the

autosampler, cycle the autosampler power switch. The autosampler sample probe should move up and the autosampler should initialize. After initialization, the status LED on the front of the autosampler should light up.

 If the cords are properly connected, power is available, the external power

supply is good, and the unit still does not initiate, continue troubleshooting or contact CETAC at CETACservice@teledyne.com.

Communications Interface Problems

Operation of the autosampler is directed by the host computer. A malfunction can indicate a problem with the RS-232 or USB cable (connected between the host computer and the autosampler) or with the configuration of the software on the host computer. The following sections explain how to troubleshoot these problems.

RS-232 Serial Cable Problems

The first step in troubleshooting communications interface problems is to check the RS-232 cable.

1 Check the RS-232 cable to ensure it is plugged in to the COM1 port on the

autosampler.

If the cable is plugged in, ensure that it is tightened properly and not damaged in any way.

Note that the cable must be plugged into the autosampler's COM1 port, not another port such as the AUX I/O port or the DILUTOR port.

2 Check the host computer to ensure that the RS-232 cable is connected to the

appropriate COM port.

If the cable is plugged in, ensure that it is tightened properly and not damaged in any way.

3 Check the serial port settings (9600, N, 8, 1).

If the wrong port or baud rate is selected, change the configuration. For information about changing the software configuration, see Chapter 4, “Verifying Installation.”

ASX-112FR Autosamplers Operator’s Manual

Chapter 7: Troubleshooting the Autosampler

USB Cable Problems

Either RS-232 or USB may be used, but not both at once.

1 Check the USB cable to ensure it is plugged into the port on the autosampler.

2 Check the host computer to ensure that the USB cable is connected to the

appropriate USB port.

3 Check that the USB cable is not damaged in any way.

4 Check the host computer to ensure that the USB drivers are installed for USB

operation of the autosampler.

Load the proper USB drivers to the host computer from the CD that was provided with the autosampler.

Software Configuration Problems

If the communication cable is connected properly and the system is still not functioning with the ICP-MS software, ensure that the software is communicating correctly with the autosampler. To do so, verify proper operation of all manual functions by completing the following steps:

1 Connect to the autosampler using a terminal emulation program (see

"Operating a CETAC Autosampler Using a Terminal Program" on page 69).

2 Enter some commands, such as HOME.

If the commands have no effect, and a USB connection is being used, check that the autosampler is plugged into the same USB port as it was when the driver software was configured. Unlike many consumer devices, each USB port used as a “virtual” COM port must be individually configured.

3 If manual commands work, but the autosampler does not operate with the ICP-

MS software, carefully check that the ICP-MS software is configured to use the COM port where the autosampler is plugged in.

If a USB connection is used, and if the manual commands work, but the ICP-MS software fails to operate the autosampler, check that the same COM port number is configured in the ICP-MS software and in the USB device driver.

Alignment Problems

An ASX-112FR Autosampler alignment malfunction may be caused by bumping the Y-arm out of alignment during a sampling sequence. If the autosampler begins missing target vials or the rinse station during a sampling sequence, complete the following:

1 Cycle the power, and restart the sequence.

The autosampler realigns to home with a power cycle.

ASX-112FR Autosampler Operator’s Manual

Chapter 7: Troubleshooting the Autosampler

If the alignment is not returned following a power cycle, check the host instrument software to ensure that the correct ASX-112FR tray configuration is being used.

If the correct tray configuration is being used and alignment problems persist, contact Teledyne CETAC Technologies Customer Service at CETACservice@teledyne.com for alignment assistance.

8 Operating a CETAC Autosampler Using a

Terminal Program

The autosampler can be controlled using a serial communications protocol. You can use any terminal emulation program, including:

 C-Term. This program is installed with the Xpress Configuration Tool

software, and runs on Windows 2000 and later. (recommended)

 HyperTerminal. This program was supplied with versions of the Windows

operating system through Windows XP.

This chapter explains how to operate a CETAC autosampler using either of the two programs.

Using C-Term ™

C-Term is a simple terminal program developed to validate the installation and functionality of various CETAC devices. C-Term communicates through a serial (RS-232) port on the host computer. If the device is connected to a USB port, the device driver will create a virtual serial port.

C-Term is provided on the CETAC software CD and is automatically installed with the Xpress Configuration Tool software.

Starting C-Term

1 Check that the communication port connectors are properly attached between

the host computer and the CETAC device.

If the communications interface between the CETAC device and the host computer is not established correctly, the device will not function.

2 On the Start Menu, click All Programs, then CETAC Xpress Config, then Support

Tools, then C-Term.

Chapter 8: Operating a CETAC Autosampler Using a Terminal Program

Figure 8-1 Starting C-Term

Overview of the C-Term Window

Once C-Term is loaded, the window shown in Figure 8-2 will open. The majority of C-Ter m’s functions are available from this window.

Figure 8-2 C-Term Window

By default, typed commands are sent to the CETAC device connected to the opened port. The typed commands will appear in light green in the terminal buffer. Responses from the device will appear in red. Non-printing characters such as carriage returns will appear as ASCII hexadecimal numbers surrounded by square brackets, for example, [0D] is the carriage return character.

ASX-112FR Autosamplers Operator’s Manual

Chapter 8: Operating a CETAC Autosampler Using a Terminal Program

Figure 8-3 Outgoing commands shown in green and incoming responses shown in red

Configuring C-Term

By default, C-Term attempts to open COM1 the first time it is executed. If the COM port that the CETAC device is connected to is not the default (COM1), then it will be necessary to configure C-Term to use the desired port.

The default communications configuration is appropriate for use with the vast majority of CETAC devices. Exceptions are the ASX-8000 which requires a baud rate change and the AS300 emulator which uses non-printing characters as part of its command protocol. Modifying the default settings is described below.

NOTE

If COM1 (or the currently selected COM port) is in use by another program or is otherwise unavailable, a warning dialog box will pop up when C-Term starts stating that the COM port could not be opened.

1 On the Tools menu, click Setup Serial Port.

Figure 8-4 Serial Port Setup Window

2 Select the desired COM port and, if necessary, the Baud rate used by the

connected device then click OK.

NOTE

Except for the ASX-8000, all CETAC devices communicate at 9600 baud (which is the default.)

NOTE

Only installed COM ports, including USB virtual COM ports, will appear in the Comm Port menu.

Setting Preferences

If desired, the size of the scrollback buffer or the color of the outgoing and incoming texts can be changed (in case of color blindness, for example).

1 On the Tools menu, click Preferences.
