ASXpress Rapid Sample Introduction System Operator’s Manual
Chapter 6: Maintaining the Rapid Sample Introduction System
Note:
It is recommended to clean the 6-port valve every 20,000 cycles.
However, the frequency of cleaning interval will vary depending on
application.
Materials required:
• dust-free work surface
• hex key wrench (provided)
• lint-free clean room wipes
• low-pressure compressed clean air (such as a canned air duster
product)
To clean the valve, complete the following steps:
1 Unplug the ASXPRESS Rapid Sample Introduction System.
2 Remove all tubing and connectors from the 6-port valve.
3 Use the hex key wrench provided to remove the three screws on the
front of the 6-port valve
Do not remove the valve body from the actuator as it will lose its position and
will require retraining if removed. Valve retraining will be discussed in detail
on page Error! Bookmark not defined..
4 Note the orientation of valve body components prior to removal.
5 Gently remove the stator of the valve.
6 Use a clean-room wiper to gently clean the channels and surfaces of
the stator and rotor of any debris.
7 Use low-pressure, canned clean air to blow the channels and ports free
of any remaining debris.
8 Very carefully replace the stator of the valve, in the proper orientation
noted in step 4, and tighten the three screws to set firmly in place.
9 Reinstall all tubing and check for leaks using the Xpress Config Tool to
“Manual Cycle” the ASXPRESS system as described in Section 4 of this
manual.
