Maintaining the Analyzers and Collision Cell
Scheduling
None of the analyzer components requires periodic maintenance. Some tasks,
however, must be performed when MS behavior indicates they are necessary.
These tasks include:
• Cleaning the ion source
• Replacing filaments
• Replacing the electron multiplier horn
See Chapter 2 , “General Troubleshooting” on page 25 for information about
symptoms that indicate the need for analyzer maintenance.
Precautions
Cleanliness
Keep components clean during analyzer maintenance. Analyzer maintenance
involves opening the analyzer chamber and removing parts from the analyzer.
During analyzer maintenance procedures, take care to avoid contaminating
the analyzer or the interior of the analyzer chamber.
Wear clean gloves during all analyzer maintenance procedures. After cleaning,
parts must be thoroughly baked out before they are reinstalled and should be
placed only on clean, lint-free cloths.
C A U T I O N
If not done correctly, analyzer maintenance can introduce contaminants into the MS.
WA R N I N G
The analyzers operate at high temperatures. Do not touch any part until you are sure
it is cool.
