Product Description

The Archon Purge and Trap AutoSam pler is designed to automate the tedious sample handling procedures associated with purge and trap analysis for volatile organic compounds (VOC's) under current EPA methods. The Archon can be used for drinking water, waste water, soil analysis, and solids. The Archon is designed as a stand-alone unit for retrofit to purge and trap instruments.

The Archon is a state-of-the art robotic, X-Y-Z axis autosampler. The AutoSampler utilizes a 51 position sam ple tray that allows water or soil samples to be run. The tray can be cooled if an optional chiller kit is ins talled. The Archon has a unique "gripper" arm which moves the sample vial to diff erent pos itions that will bar code read (optional), identify the vial type, stir the sample, equilibrate to room temperature, and transfer the sample to the water or soil probe position.

When running s oil samples, the Archon automates heated purge and trap. The soil sample may be placed in the patented SoilVial, or if the Archon is s etup for needle sparging, a standard 40 mL VOC vial. A stirring bar (optional) is added, the cap with a low bleed septum is replaced, and the entire vial placed in the sample tray. The robotic arm transfer s the vial to the vial identification step, and then lifts the vial into the heated chamber where water is added, with one or both standards, the sample is then purged directly onto the trap of the concentrator.

1 Introduction

If a water sample is to be run, the sample is placed in a 40 mL VOC vial and a stir bar (optional) is placed in the vial and the vial is placed in the tray. The Ar chon robotic arm moves the vial to the vial ID station and then to the pr obe location where it is lifted onto the sample probe, and a program med volume of water is transferred to the purge vessel. It is during the transfer that one or both of the standards are added to the sample. It will also drain and c lean the needle, s parge tube, and transfer lines.

The operating modes of the Archon are the Automatic, Manual, and Flush modes. Automatic mode allows for complete unattended operation. Manual mode operation allows for single sample operation of the unit, priority sampling, and running blanks. The Flush m ode perform s the flushing with hot water and helium for the cleanup of the system. All modes perform per their programmed method.

The Archon is easily programmed through its own color-coded keypad. Programming is m enu driven and displayed on an LCD screen. Parameters can be read and altered and the screen displays the function in progress during the run.

The Archon interfaces directly with the Tekmar LSC 2000, 3000, OI 4460A, 4560 and other purge and trap units.

1.4.3 Interior

Introduction

Refer to Figure 1-3. Sample Tray (not shown): A 51 position, all aluminum, sam ple tray is provided

to hold sample vials. The tr ay is removable, and when installed, rests on top of the aluminum tray cooler for cooling the samples.

1. Robotic Arm: The robotic arm is used to move the sample vials. A vial gripper is used to remove the vials from the tray and place them in the appropriate sampling positions.

2. Water Probe: The water probe is a patented concentric needle to puncture water vials, pressurize, and displace water samples to the syringe. After sampling, the probe is rinsed in a chamber that prevents sample from spraying onto the instrument components.

3. Soil Probe: The patented soil probe and the Needle Sparge probes incorporate a "T" fitting design for attachment of water and heated transfer line. The probe is installed in a heated oven and easily removable for cleaning or replacement.

4. 26 mL Syringe: A 26 mL syringe is used to move sam ple, blank, flush and waste water. The syringe is mounted upright, directly into the valve manifold.

Figure 1-3

5. Standard Valve: The standar d injection station uses a 6 port valve with a 1 µL internal loop. The internal standard groove is filled by pressurizing the standard reservoir and rotating the valve to positions 1 & 2, (Std. 1, Std.

2).Water samples or dilution water passes through the loop to deliver the

Parameter Range Default Description

Operate Mode Local /

Remote

Cycle Timer 0-99.9 min. 00.0 min.

This Mode determines if the Archon will depend on switch signals from the purge and trap to advance, or be dependent on the Cycle Timer. In the “Local” Mode, the Archon will start when the Cycle Timer parameter, set in the method has elapsed. NOTE: In Local, the Ar chon will NOT respond to switch signals from the purge and trap, i.e. Standby (Ready) and Desorb Ready. In the “Remote” Mode, the Archon responds to the switch signals given by the purge and trap and the Cycle Timer parameter. Once the purge and trap reaches its Standby mode, a signal output will start the Archon, provided the Cycle Timer has reached 0.0.

This will advance the Archon from a ready to sample mode. T he Archon starts when a purge ready signal is received from the purge and trap, in the standby mode. The cycle includes the purge time, plus the GC run time and cool down. The cycle time is normally used to ensure that the GC will be ready to receive the next sample. In the case of short GC run times, cycle time will not be effec tive, and should be set to "0.”

The Archon will continue the sampling sequence for this method upon completion of the current selected method. Any combination of methods may be linked together providing for continuous operation. Note: Circular linkage of a method is allowed, i.e., linking a method to itself to continually cycle through one method. Set the parameter to "0" to stop the autosampler after the last vial in the method.

5.3

Blanks After Vial Editing

Single blank runs can be programmed after specific sample vials within a particular method. These are known as "Method Blanks" and complement the alternative of creating a whole method where all of the runs are blanks.

Method blanks are particularly useful when analyzing sample sets containing both high and low concentration samples. T he blank s allow additional s ystem cleaning of not only the Archon, but also of the Purge and Trap and the GC. T he blank water is withdrawn from the blank water reservoir rather than a user-prepared vial, but otherwise is followed by the whole analysis sequence. Method blanks can also be used to confirm that cross-sample contamination has not occurred.

To program Method Blanks, build the rest of the method first entering the parameters under the <Edit Method> m enu. Then press the "Method" k ey to exit to the *METHOD* menu. Scroll down to <Edit Blank Vials> and press Enter.

The *Method Blanks* menu, as shown, will allow the programming of a single blank water run after any of the sample vials in the method. Note that the vial numbers for which a following blank may be programmed are restricted to the range defined by the <First Vial> and <Last Vial> entries in the earlier method parameters.

Method Setup

*METHOD#BLANKS* <Vial#= Blanks= YES (NO)> U/D changes vial. L/R changes blank.

Equilibrium Count and Equilibrium Time

The Equilibrium Count and the Equilibrium Time parameters allow samples cooled with the optional tray-cooling system to be equilibrated to warmer temperatures before analysis. Because tray cooling affects all samples regardless of method, the Equilibrium Tim e par am eters ar e actually set within the “system settings” menus, (see Section 6.6). They are discussed here for continuity. The Equilibrium Count is the number of vials (5 is the max imum ) to be placed in the Equilibrium zone station for temperature equilibrating, see Figure

6.4.8 Manual Calibration: Coordinate Settings M enu I tems

The remaining menu items of the Calibration Setup menu allow manual calibration of specific positions of the robotic arm and gripper. These are used less frequently than the automated routines, primarily in the initial instrument setup and particular troubleshooting situations. Thes e routines allow the user to move the arm or gripper increm entally until the user determines that the correct position has been achieved. The user then saves the position coor dinates to the Archon memory.

System Setup

The routines also allow the user to directly enter a position value determined by other means. Note that the original positional settings determined at the f actory during the instrument's manufacture are recorded on the reference sheet attached to the inside of the Archon right chassis panel. In certain instances, it may be useful to directly re-enter these original values through the Manual Calibration menu items.

When a m anual calibration routine is chosen from the Calibration Setup m enu, the screen will display a new Coordinate Settings menu of the general format shown below. The title and other minor features will differ to be appropriate for the task. The menu allows the user to adj ust positions along one axis at a tim e. The axis currently addressed is shown on the last (fourth) line with the numer ic step value of the current position. The sec ond and third menu lines list the num eric commands for moving the arm or gripper along that axis.

Ignore Vial Type:

If the Archon is equipped with an optional Barcode Scanner, answering “YES” will tell the Archon Robotic Arm to place the sample vials in the Barcode Scanner Zone prior to vial type detection. The barcode label on the vial will be read and the information m ay be retrieved to a PC for its use. Only one barcode label will be retained for each vial position.

If the Archon is setup for Needle Sparge sampling, this option must be “YES.” The sample vial type sensor will then be reversed to detect water (40 ml VOC) vials. If a SoilVial is detected, an error will be reported.

This option disables the sample vial sensor . W hen “YES" is selected, only the “sample type" parameter will determine the sampling loc ation. See “Method Setup” for further details.

Beep on Error:

When this option is “YES,” tray positions that have no vials will be ignored. The Gripper “No Vial” sensor will always be used to detect the presence of a vial and the potential of lost vials in transit. The default should be “NO”.

When this option is “YES”, the “Hot Water" reservoir is heated during the syringe and sparge tube rinses. This reservoir is located inside the rear or the unit. Water passes through the heated reservoir prior to entering the 25 ml syringe and sample transfer lines.

This option will cause the Robotic Arm to search the equilibrium and vial sampling locations for vials during start-up. The Archon will remove the vials and return them to the sample tray.

CAUTION

This option should be set to “YES” to prevent vial jams. This option causes the Archon to produce an audible

“Beep” when a System error occurs. The beep will sound every five seconds. This would be anything which may interrupt or stop the sample run. If a problem occurs and the Archon “Beeps”, immediate action must be taken to resolve the problem. An error message should be displayed indicating the problem.

WAR NING:

BURN HAZARD

Components may be hot! Be certain the “UPPER SOIL PROBE TEMP” and “UPPER SOIL VALVE TEMP” are OFF and the parts are cool before continuing.

1. Remove the soil probe cover. Disconnect the short line heated upper soil valve Load a clean vial with a new septum in the tray and run it as a manual soil sample. Check the flow rate out of the line. It should be the sam e as the f low from the soil probe bulkhead nut

2. If the two flow rates are not equal, replace the vial and septum and repeat the soil purge. If the flows still do not m atch, the soil pr obe m ay be dam aged and should be replaced. See Section 7.1.

3. If the f lows do match, chec k the flow com ing out of the upper soil valve A “jig” should be made to test the flow. Remove the transfer line upper soil valve. Using a 2-3" (5.0 cm - 7.5 cm ) piece of 1/16" OD stainless steel tubing, a Valco nut and a two piece compress ion ferrule, insert the jig into the valve and tighten. Measure the purge flow out of the jig. The flow should be equal to the flow from the shortline

4. If the flows do not match, the upper soil valve is leaking, and it should be replaced.

5. If the flows do match, the fitting on the end of the soil transfer line in the purge and trap may be leaking, or a leak exists within the purge and trap.

6. Reattach the transfer line into the upper soil valve and recheck the flow at the host purge and trap vent. If the flows do not match, check the fitting, on the soil transfer line, in the purge and trap, and leak check the host purge and trap per its recommendations.

7. Using isopropanol and water, recheck all the fittings again to insure that they are leak tight. Once these steps have been completed and the flow rates now match, the system is leak tight and ready for use.

When connecting to a Varian series 3400 or 3600 GC with Star Workstation, connectors from both the Archon I/O cable and the Star Workstation cable must access the J16 and J23 connectors on the GC motherboard. This is possible using the J16 Splitter (DY-700030-00) and the J23 Splitter (DY-700031-00) following the instructions below:

1) Turn off the power and unplug the power cord f rom the GC. Remove the top panels to allow access to the GC motherboard.

2) Route the GC-end of the Arc hon I/O cable and the GC-end of the Star W orkstation cable through the back panel of the GC (see Star Workstation installation diagram).

3) Connect the 5-pin female Molex connec tor (P-23) from the Star Workst ation cable to the male connector on the J-23 Splitter with 4 pins (the #2 position lacks a pin).

4) Connect the 5-pin female Molex connector from the Archon I/O cable to the 5-pin male connector on the J-23 Splitter.

5) Connect the J-23 Splitter to the J-23 connector on the GC motherboard (see GC manual for motherboard layout schematic).

6) Connec t the 4-pin female Molex connector from the Archon I/O cable to either of the 4-pin male connectors on the J-16 Splitter.

7) Connect the 4-pin female Molex connec tor (P-16) from the Star Workst ation cable to either of the 4-pin male connectors on the J-16 Splitter.

8) Connect the J-16 Splitter to the J-16 connector on the GC motherboard (see GC manual for motherboard layout schematic).

9) Complete the installation of the Archon I/O cable and of the Star Work station cable according to the standard instructions for those cables.

Technical Note: The following sequence occurs when the Archon and a Purge and T rap unit is configured with the Varian 3400 and 3600 GC with Star Workstation:

1) The Archon begins its sample handling after receiving a Ready signal from the Purge and Trap unit. As configured above, the Purge and Trap goes to Ready without waiting for the GC. This allows the user to prepar e the GC or W orkstation while the sample is being purged and collected in the Purge and Trap.

2) The Purge and Trap collects the purged sample onto its trap and waits for a Ready signal from the GC. This occurs after the Workstation issues a Ready signal to the GC through the Workstation’s cable plug attached to the GC’s J-16 “Ready-In” pins, 1 and 2. In turn, the GC sends a “Ready-Out” signal from its J-23 pins 1 and 3 into the Archon I/O cable.

3) When the Purge and T rap has both com pleted its purge cycle and detec ted a Ready signal from the GC, the Purge and T rap desorbs the s ample from its trap and issues a “Desorb-Out” signal to both the Archon and to the Var ian GC. This signal travels through the Remote I/O cable supplied with the Archon.

4) The Desorb- Out s ignal f rom the Purge and Trap starts the Arc hon’s “AutoDr ain” c ycle which drains the sparge vessel if a water-sample method is being run on the Archon.

5) The Desorb-Out s ignal simultaneously travels through the Archon Remote I/O cable to its connector attached to the GC’s J-16 Start-In pins, 3 and 4, and initiates the GC run. The GC in turn initiates a “Start-O ut” signal through J-23 pins, 4 and 5, which triggers the Workstation to begin data collection.

sample. In Slave mode, the GC/MS or data s ystem c ommands or signals the T ek mar unit to start processing a sample.

This interface has two cables , Master and Slave control. If you install the Master cable, the unit will operate in Master mode. If you install the Slave control cable, your system will operate in Slave. If you are using Revision F or greater HP software, install both cables. O therwise choose the mode to use and install the appropriate cable. Use these guidelines:



If your software is not Revision F or greater and you have a cryofocusing module installed in

your system, install the Master cable. Do not install the Slave cable.



If your software is not Revision F or greater and you do not have a cryofocusing module

installed, decide which system suits your needs.

If the total cycle time is shorter than the G C/MS c ycle tim e, ins tall the s lave c able. T his will ins ur e the Archon and 3000 are ready when the GC/MS gives the start signal.

If the GC/MS cycle time is shorter than the Arc hon and 3000, install the m aster cable. When in Master mode, be certain the GC/MS is ready when the start signal is given.

Connections:

Master Cable

1. Locate the remote start button on the GC/MS.

2. Locate the Master cable. Note drawing.

3. Connect the Master cable to the receptacle on the rear of the remote start button.

Slave Cable

1. Locate the Molex plug labeled “Accessory Connection” on the rear of the GC/MS.

2. Remove the Molex plug from the remote start button.

3. Locate the Slave cable. Note drawing.

4. If you have Revision F or greater software, attach the two pins, from the Slave cable, to position 27 and 28 on the Molex plug. It does not matter to which position each pin attac hes. If you do not have Revision F or greater, attach the two pins, from the Slave cable, to position

25 and 26 on the Molex plug. It does not matter to which position each pin attaches.

GC/MS Programming Guides

1. If your software is Revision F or greater: Select MNUAL under INJECTOR CONTROL.

2. If you are using DATAC in Slave mode: Select relay #1 - ON 0.1 min.; OFF 0.2 min.

3. If you are using BATCH SEQ UENCE in Master mode, select the following: Bottle #1 ( use remote start button.), ALS stroke 1.

4. If you are using BATCH SEQUENCE in Slave m ode, select the f ollowing: Bottle # 0 (non-HP autosamplers), ALS stroke 1, Relay #1 ON, 0.10 min; OFF 0.2 min.
