Maintaining the analyzer
The analyzer requires no periodic maintenance
None of the analyzer components requires periodic maintenance. Some
tasks, however, must be performed when MSD behavior indicates they are
necessary. These tasks include:
• Cleaning the ion source
• Replacing filaments
• Replacing the electron multiplier horn
Chapter 3, Troubleshooting the MSD, on page 65 provides information
about symptoms that indicate the need for analyzer maintenance. The
troubleshooting material in the online help in the MSD ChemStation soft-
ware provides more extensive information.
Care must be taken during analyzer maintenance to keep
components clean
Analyzer maintenance involves opening the vacuum manifold and removing
parts from the analyzer. During analyzer maintenance procedures, care
must be take to avoid contaminating the analyzer or interior of the vacuum
manifold. Clean gloves should be worn during all analyzer maintenance
procedures. After cleaning, parts must be thoroughly baked out before they
are reinstalled. After cleaning, analyzer parts should be placed only on clean,
lint-free cloths.
