5 General Maintenance
The oil trap supplied with the standard foreline pump stops only foreline pump
WAR N IN G
oil. It does not trap or filter out toxic chemicals. If you are using toxic solvents
or analyzing toxic chemicals, remove the oil trap. Do not use the trap if you have a
CI MSD. Install a hose to take the foreline pump exhaust outside or to a fume hood.
The fluids in the diffusion pump and standard foreline pump also collect traces
of the samples being analyzed. All used pump fluid should be considered
hazardous and handled accordingly. Dispose of used fluid correctly, as specified
by your local regulations.
When replacing pump fluid, use appropriate chemical-resistant gloves and
WAR N IN G
safety glasses. Avoid all contact with the fluid.
Electrostatic discharge
All of the printed circuit boards in the MSD contain components that can be
damaged by electrostatic discharge (ESD). Do not handle or touch these boards
unless absolutely necessary. In addition, wires, contacts, and cables can conduct
ESD to the electronics boards to which they are connected. This is especially true
of the mass filter (quadrupole) contact wires which can carry ESD to sensitive
components on the side board. ESD damage may not cause immediate failure,
but it will gradually degrade the performance and stability of your MSD.
When you work on or near printed circuit boards or when you work on
components with wires, contacts, or cables connected to printed circuit boards,
always use a grounded antistatic wrist strap and take other antistatic
precautions. The wrist strap should be connected to a known good earth ground.
If that is not possible, it should be connected to a conductive (metal) part of the
assembly being worked on, but not to electronic components, exposed wires or
traces, or pins on connectors.
Take extra precautions, such as a grounded antistatic mat, if you must work on
components or assemblies that have been removed from the MSD. This
includes the analyzer.
To be effective, an antistatic wrist strap must fit snugly (not tight). A loose
C AU T I O N
strap provides little or no protection.
Antistatic precautions are not 100% effective. Handle electronic circuit boards
as little as possible and then only by the edges. Never touch components,
exposed traces, or pins on connectors and cables.
