General Maintenance 4
5975/5977 Series MSD Operation Manual 93
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
wires which can conduct ESD to sensitive components on the side board. ESD
damage may not cause immediate failure but will gradually degrade
performance and stability. See page 90 for more information.
Some analyzer parts should not be disturbed
The mass filter (quadrupole) requires no periodic maintenance. In general, the
mass filter should never be disturbed. In the event of extreme contamination,
it can be cleaned, but such cleaning should only be done by a trained Agilent
Technologies service representative. The HED ceramic insulator must never be
touched.
More information is available
If you need more information about the locations or functions of analyzer
components, refer to the Agilent 5977B Series MSD Troubleshooting and
Maintenance Manual.
Many procedures in this chapter are illustrated with video clips.
CAUTION
Electrostatic discharges to analyzer components are conducted to the side board
where they can damage sensitive components. Wear a grounded antistatic wrist strap
(see page 90) and take other antistatic precautions before you open the analyzer
chamber.
CAUTION
Incorrect handling or cleaning of the mass filter can damage it and have a serious,
negative effect on instrument performance. Do not touch the HED ceramic insulator.
