Operation Manual
An oil mist filter is supplied with the standard foreline pump.
This filter stops only pump oil droplets. It does not trap any
other chemicals. If you are using toxic solvents or analyzing
toxic chemicals, install a hose from the mist filter outlet to the
outdoors or into a fume hood vented to the outdoors. 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 does not trap or filter out toxic chemicals. If you
are using toxic solvents or analyzing toxic chemicals, use a hose to
vent to a safe location.
The fluids in the 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 as
specified by your local regulations.
When replacing pump fluid, use appropriate chemical-resistant
gloves and safety glasses. Avoid all contact with the fluid.
The main effect of operating the MS in CI mode is the need for
more frequent ion source cleaning. In CI operation, the ion
source chamber is subject to more rapid contamination than in
EI operation because of the higher source pressures required
for CI.
Always perform any maintenance procedures using hazardous
solvents under a fume hood. Be sure to operate the MS in a
well-ventilated room.
