The instrument is separated into the electronics and analyzer compartments.
The electronics compartment includes the
•
Scan acquisition processor/waveform board (SAP/Wave board)
•
Power board
•
The analyzer compartment includes the
•
Transfer line
•
Vacuum manifold (including the ion trap)
•
Vacuum pump and controller
•
RF coil and generator
•
Pneumatics manifold
Mechanical Assemblies
The Saturn mechanical assemblies include the following:
•
Controls and indicators
•
Cooling fans
•
Vacuum system
•
Transfer line
•
Ion trap assembly
Controls and Indicators
The main power switch for the Saturn GC/MS, located on the rear panel, controls
power to the vacuum system and to the electronics.
When the main power switch is turned on, the light-emitting diode (LED) on the
Saturn GC/MS front panel is illuminated.
In the event of an emergency, shut off of all power to the Saturn GC/MS by
placing the main power switch in the OFF position and unplugging the
