Pumping Down

The data system helps you pump down the MSD. The process is mostly
automated. Once you close the vent valve and turn on the main power switch
(while pressing on the sideplate), the MSD pumps down by itself. The data
system software monitors and displays system status during pumpdown. When
the pressure is low enough, the program turns on the ion source and mass filter
heaters and prompts you to turn on the GC/MSD interface heater. The MSD will
shut down if it cannot pump down correctly.

From the Instrument Status Dashboard, OpenLAB CDS can display:

•

Motor speed for turbo pump MSDs (percent spin speed)

•

Foreline pressure for diffusion pump MSDs

•

Analyzer chamber pressure (vacuum) for MSDs equipped with the optional
Micro-Ion Gauge Controller (G3397A for the 5975 and G3397B for the 5977).

Controlling Temperatures

MSD temperatures are controlled through the data system. The MSD has
independent heaters and temperature sensors for the ion source and quadrupole
mass filter. You can adjust the setpoints and view these temperatures from the
data system or from the local control panel.

Normally, the GC/MSD interface heater is powered and controlled by the Thermal
Aux #2 heated zone of the GC. The GC/MSD interface temperature can be set
and monitored from the data system or from the 7890B GC control panel.

Controlling Column Flow

Carrier gas flow is controlled by inlet pressure in the GC. For a given inlet
pressure, column flow will decrease as the GC oven temperature increases. With
electronic pneumatic control (EPC) and the column mode set to

Constant Flow

,

the same column flow is maintained regardless of temperature.

The MSD can be used to measure actual column flow. You inject a

small

amount

of air or other unretained chemical and time how long it takes to reach the MSD.
With this time measurement, you can calculate the column flow. See
