ASX-560 / ASX-280 Autosampler Operator’s Manual
Chapter 1: Introduction
Chemical Compatibility
The autosampler operates reliably under a wide variety of conditions. No
metallic components are exposed above the sample vials. The top cover and
base are made from polypropylene. The arm and Z-drive are made from carbon
fiber.
The back and frame are made from a high-strength aluminum alloy that is
treated with a RoHS-compliant chemfilm and finished with an epoxy powder
coating. Long-term exposure to aqueous acids greater than 15% may cause
discoloration or bubbling of the epoxy coating.
Internal splash shields protect against occasional exposure to corrosive
chemicals. The covers are not sealed against liquid or vapor intrusion. Longterm exposure of the internal components to corrosive materials may cause
damage.
Exposure to corrosive vapors can be minimized by using an enclosure with
airflow directed down and away from the electronic components.
Components in the sample flow path are made of polyetherimide (PEI) and
polytetrafluoroethylene (PTFE). When these inert, non-metallic materials are
used at temperatures less than 135 °C, they can withstand repeated exposure
to the following substances:
CAUT ION
WARNING
Predominantly aqueous solutions of strong acids (less than 20%)
Predominantly aqueous solutions of strong bases (less than 10%)
Common organic solvents such as acetone, alcohols, ethyl acetate,
methylethylketone (MEK), petroleum oils and derived fuels, and kerosene.
DAMAGE FROM CHEMICAL EXPOSURE
Prolonged or repeated exposure to temperatures greater than 135 °C and to the
following substances can cause failure of the flow path components:
• Solutions of concentrated acids (greater than 40%).
• Solutions of concentrated bases (greater than 10% potassium, ammonium, or
sodium hydroxides).
• Partially halogenated hydrocarbons or extremely aggressive organic solvents
(chloroform, methylene dichloride, 1,1,2-trichloroethane).
Prolonged exposure to carbon tetrachloride can damage the autosampler.
CHEMICAL HAZARD
Do not use the autosampler with substances which could pose a hazard of
serious injury to the operator if spilled or injected, such as biological
substances or formic acid.

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.
Choosing a Location
For the system to function optimally, the location you select must meet specific
requirements.
Space Requirements
Most analytical applications benefit from using 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 tables.
Height 28 cm (14")

Work Surface Requirements
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.
CAUT ION
WARNING
Rinse Solution Requirements
For most applications, deionized water or kerosene is used as the rinse agent.
Place the rinse agent source within two meters of the autosampler.
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 autosampler rinse station outlet and set up so that the rinse drain
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.
Power Requirements
The autosampler is powered by the supplied external desktop "brick" power
supply. Place the autosampler within 1.2 meters of a power outlet.
SHOCK AND FIRE HAZARD
Use only the provided power supply. The power supply must be plugged
into an outlet which has a protective ground connection.
The autosampler is intended to operate from DC power supplied through the
provided power supply. The power supply is provided power through an AC
16
ASX-560 / ASX-280 Autosampler Operator’s Manual
17
Chapter 2: Preparing for Installation
power source that will not apply more than 240 VAC between the supply
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) so that 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 below the power
switch. 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
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 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.
CAUT ION
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.

ASX-560 / ASX-280 Autosampler Operator’s Manual
Chapter 3: Installing the Autosampler
Connecting the Rinse Station
The rinse station is mounted to the tray of the autosampler, at the left end of
the standards rack.
Typically, deionized water, an acid rinse such as a 2% HNO
, or a solution from
3
the kerosene family, is used as the rinse solution.
The rinse solution flows from the sample probe reservoir to the drain (rinse
out) reservoir within the rinse station. The waste rinse solution is then drained
from the rinse station.
The inlet of the rinse station is at the bottom of the rinse station. The rinse
solution flows from the bottom to the top of the sample probe reservoir. Upflow rinsing is the most effective method for decontaminating the sample
probe tube between samples. Reversing the connections will reverse the flow
direction, resulting in cross-contamination and unsatisfactory performance.
Waste Rinse Solution
In most cases, rinse solution will be “recycled” by returning it to the rinse
solution bottle. If necessary, rinse solution can be pulled from a fresh bottle
and used solution drained to a waste container. Remember to label the waste
container according to your laboratory policy and local regulations.
Ensure that the tubing outlet is placed so that it will remain above the surface
of the liquid in the waste container. If the end of the tube is immersed, the
waste solution might back up and overflow.
Tubing Considerations
Verify that the supplied tubing material is compatible with the rinse solution
you are using. There are many different types of tubing that can be used for the
rinse station. Clear Tygon
(yellow), and PharMed
depending on the application and user preference. Clear Superthane
can used everywhere other than the pump tubing. Contact CETAC if you need
different tubing material.
The fittings on the rinse station use
fittings on the peristaltic pump use smaller ⅛ inch (3.2 mm) ID tubing. If
tubing needs to be replaced, a tubing kit with a adapter fittings can be ordered
from CETAC.
®
tubing is provided. Viton®, Tygon® Fuel and Lube

/16 inch (4.8 mm) ID tubing, but the
®
tubing
Carefully press the tubing straight on to the fittings to avoid breaking the
fittings. If you find it difficult to get a good connection to the rinse station,
remove the rinse station and press the tubing firmly so that it completely
covers the barb of the fitting. It helps to use your other hand to apply counterpressure.

Chapter 3: Installing the Autosampler
Pumped Drain Arrangement
In a pumped drain arrangement, one channel of the peristaltic pump to supply
rinse solution to the rinse station, while the other channel of the pump drains
the used rinse solution.
