1 Make sure your system meets all of the following conditions
before you pump down:
The vent valve is closed (the knob is turned all the way
clockwise).
All other vacuum seals and fittings are in place and
fastened correctly. (The front side plate screw should not
be tightened.)
The MSD is connected to a grounded power source.
The GC/MSD interface extends into the GC oven.
A conditioned capillary column is installed in the GC
inlet and in the GC/MSD interface.
An inlet, septum, liner, and O-ring are clean, installed and
in good condition.
A column is installed, in the transfer line.
A source is installed.
The GC is on, but the heated zones for the GC/MSD
interface, the inlet, and the oven are off.
Carrier gas of at least 99.999% purity is plumbed to the
GC with the recommended traps.
If hydrogen is used as carrier gas, carrier gas flow is off
and the front sideplate thumbscrew is loosely fastened.
The foreline pump exhaust is properly vented.
Make sure your MSD meets ALL the conditions listed above. Failure
to do so can result in personal injury.
