Maintaining The Analyzer - Agilent Technologies 5977B Series Operating Manual

6 General Maintenance

Maintaining the Analyzer

Scheduling
None of the analyzer components require 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
The Agilent 5977B Series MSD Troubleshooting and Maintenance Manual
provides information about symptoms that indicate the need for analyzer
maintenance. The troubleshooting material in the online help in the Agilent
MassHunter GC/MS Acquisition software provides more extensive
information.
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. After cleaning, analyzer parts should be
placed only on clean, lint-free cloths.
If not done correctly, analyzer maintenance can introduce contaminants into the MSD.
C A U T I O N
The analyzer operates at high temperatures. Do not touch any part until you are sure
