Temperature Symptoms
The MS has three heated zones:
• Ion source
• Mass filter
• GC/MS interface
Each heated zone has a heater and temperature sensor. The ion source and
mass filter are powered and controlled by the MS. The GC/MS interface is
powered and controlled by the GC.
Ion source will not heat up
• High-vacuum pump is off or has not reached normal operating conditions*
• Incorrect temperature setpoint
• Ion source has not had enough time to reach temperature setpoint
• Ion source heater cartridge is not connected*
• Ion source temperature sensor is not connected*
• Ion source heater failed (burned out or shorted to ground)*
• Ion source temperature sensor failed*
• Source power cable is not connected to the quadrupole board*
• MS electronics are not working correctly
