Chapter 5: Using the Rapid Sample Introduction System
• 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 the use of maximum care.
WARNING
Discharge static buildup and ground to the ASXPRESS Rapid Sample
Introduction System base or cabinet before performing any
maintenance. Do not touch or short-circuit bare contacts.
Avoid using the ASXPRESS Rapid Sample Introduction System if strong
electromagnetic interference, radio frequency interference, or radioactivity is
present. Interference fields can cause erratic. The ASXPRESS Rapid Sample
Introduction System will not function properly if the level of radioactivity is
above background.
5.1.2 Replacing Rapid Sample Introduction System
Components
The following ASXPRESS Rapid Sample Introduction System components wear
out under normal use and must be replaced periodically. These components
are consumables and replacement is not covered under warranty. The
lifecycle of these components vary considerably depending upon the
application and solids content of the sample being transported. Approximate
lifecycle ranges are listed as follows:
‣ 6-Port Injection Valve (5K – 60K cycles – dependant on solids levels)
‣ Vacuum Pump (10k – 500K cycles – dependant on solids levels)
‣ Tubing (user/application determined)
‣ Sample Loop (user/application determined)
If you fail to replace these components when/before they deteriorate, the system
will not function properly. For information about replacing components, see
Chapter 6, “Maintaining the Rapid Sample Introduction System.”
