Operation Manual
Verify the following before you turn on or attempt to operate the
MS.
• All vacuum seals and fittings must be in place and fastened
correctly. The analyzer plate thumbscrew should be
unfastened, unless hazardous carrier or reagent gases are
being used.
• The MS is connected to a grounded power source.
• The GC/MS interface extends into the GC oven.
• A conditioned capillary column is installed in the GC inlet
and in the GC/MS interface.
• The GC is on, but the heated zones for the GC/MS interface,
the GC inlet, and the oven are off.
• Carrier gas of at least 99.9995% purity is plumbed to the GC
with the recommended traps.
• The use of hydrogen gas is specifically prohibited with this
product.
• The foreline pump exhaust is properly vented.
The exhaust from the foreline pump contains solvents and the
chemicals you are analyzing. The standard foreline pump, also
exhausts traces of pump oil. If you are using toxic solvents or
analyzing toxic chemicals, attach a hose (11-mm id) to the oil mist
filter to take the foreline pump exhaust outside or to a fume
(exhaust) hood. Be sure to comply with local regulations. The oil
mist filter supplied with the standard pump stops only pump oil. It
does not trap or filter out toxic chemicals.
The use of hydrogen gas is specifically prohibited with this product.
