Electrostatic discharge
The wires, contacts, and cables connected to the analyzer components can carry
ESDs to the electronics boards to which they are connected. This is especially
true of the mass filter (quadrupole) and CC contact wires which can conduct ESD
to sensitive components on the quad driver board. ESD damage may not cause
immediate failure but will gradually degrade performance and stability. (See
“Electrostatic discharge” on page 151 for more information.)
Analyzer parts that should not be disturbed
The mass filters (quadrupoles) and the CC require no periodic maintenance. In
general, the mass filters should never be disturbed. In the event of extreme
contamination, they can be cleaned, but such cleaning should only be done by a
trained Agilent Technologies service representative.
More information is available
If you need more information about the locations or functions of analyzer
components, refer to the Agilent 7000/7010 Series Triple Quad GC/MS
Troubleshooting and Maintenance Manual.
Electrostatic discharges to analyzer components are conducted to the quad
driver board where they can damage sensitive components. Wear a grounded
antistatic wrist strap. (See “Electrostatic discharge” on page 151.) Take other
antistatic precautions before you open the analyzer chambers.
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.
