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.

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.

 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.
