Symptom Cause Remedy
1. Filament will not turn on
(Unable to turn on
filament error! on user
interface.) 1a. Remove Ionizer source and
check to see if filament has
opened. 1a. If opened, replace ion source
(see
section 16.8, Replacing the
Ionizer of the Mass Spectrometer,
on page 16-41
), otherwise contact
Customer Support (see Chapter
18 ).
2. Filament shut off. (Over
pressure fault.) 2a. System shuts down filament if
pressure spikes. An old Ion Pump
will "burp" N
2
and Ar which can
cause the system to shut down.
2a. Replace Ion Pump. Contact
Customer Support (see
Chapter
18 ).
2b. System has an air leak. Turn
off carrier gas and check to see if
mass 32 is relatively large (10 to
20% of peak 28) 2b. Contact Customer Support
(see
Chapter 18 ).
2c. MDP/Turbo Pump or Roughing
Pump may need servicing. 2c. Check Turbo Speed in the

Pump installed. 3a. Contact Customer Support
(see
Chapter 18 ).
3b. Short in Electron Multiplier, or
fault in high voltage power supply 3b. Contact Customer Support
(see
Chapter 18 ).
4. Poor sensitivity in Tune. 4a. Ionizer has degraded. 4a. Replace Ionizer using
