General Maintenance
Maintaining the Analyzer
Scheduling
None of the analyzer components require periodic maintenance. Some tasks,
however, must be performed when GC/MSD behavior indicates they are
necessary. The Agilent 5975T LTM GC/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 ChemStation 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 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. It is recommended that a spare, clean EI
source be ready to install when the source in use needs cleaning. For
information on how to clean an EI source, refer to the Agilent 5975T LTM
GC/MSD Troubleshooting and Maintenance Manual.
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
WA R N I N G
it is cool.
Some parts can be damaged by electrostatic discharge
The wires, contacts, and cables connected to the analyzer components can
carry electrostatic discharges (ESD) to the electronics boards to which they
are connected. This is especially true of the mass filter (quadrupole) contact
