pumps, install a hose to take the exhaust from the foreline pump outdoors or
into a fume hood vented to the outdoors. For the standard foreline pump, this
requires removing the oil trap. Be sure to comply with your local air quality
regulations.
The oil trap supplied with the standard foreline pump stops only foreline pump oil. It
WARNING
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 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
exposed wires or traces, or pins on connectors.
