Turning Off the Mass Spectrometer
WARNING:
BURN HAZARD
Allow heated zones to cool before disassembly.
1. Shut down the mass spectrometer through the Startup/Shutdown tab in
System Control. Click the Shut Down button in the upper left corner of the
screen. The heaters will be turned off and the speed of the turbo pump will
be gradually reduced to 35% of full speed. It may take several hours for full
shutdown and cooling to take place.
To speed the shutdown process, the system can be powered down and
purged with Nitrogen. See “Turning Off the Mass Spectrometer with Nitrogen
Purge” (page 36).
