Cleaning the System
Cleaning the ASXPRESS PLUS Rapid Sample Introduction System is the primary
maintenance task you perform. Failure to do so regularly causes increased
wear and reduces the system’s life.
You must clean the ASX
PRESS PLUS Rapid Sample Introduction System both daily
and weekly to protect the instrument, prevent damage and extend its life. It is
especially important to clean up spills which may infiltrate the instrument
case/cabinet whereby damage to components may result. It may also be
necessary to chemically neutralize spills. The following sections explain daily
and weekly cleaning procedures.
Daily External Cleaning
The ASXPRESS PLUS Rapid Sample Introduction System is often operated in
environments where spills and exposure to vapors is common. Good
maintenance requires that you clean the system daily. To do so, complete the
following steps:
1 Unplug the ASXPRESS PLUS Rapid Sample Introduction System power/signal
cable from the autosampler.
2 Wipe the cabinets (electronics module and valve/pump module) using a clean-
room wipe dampened with deionized water.
Avoid scratching the cover while drying. The ASXPRESS PLUS system must be
thoroughly dry before you turn the power on again.
Cleaning the Filters
If your configuration includes a diaphragm pump, the in-line filters before the
pump intakes require periodic cleaning or replacement. If the flow of rinse
solution is reduced, or if the rinse station isn’t filling completely, it is time to
clean or replace the filters.
Most configurations use disposable in-line 75-micron filters. See the ASX
PRESS
PLUS Rapid Sample Introduction System Accessories and Supplies Catalog for
information on ordering replacements.
Figure 11-1 Disposable In-Line Filter
A few systems may use a larger filter which can be opened for cleaning. To
clean the filter:
1 Turn off the autosampler and the ASXPRESS PLUS electronics module.
