Electron Multiplier / V-Stack Detector
The multiplier is immune to up-to-air cycling and routine low-level ion bombard-
ment. However, over time the system will begin to lose gain. When this becomes
unacceptable, a new multiplier will restore the original gain of the system.
Call AMETEK Process Instruments or your local representative to
arrange for factory service to replace the multiplier. Because of the
complexity of the detector flange assembly, we recommend that the
multiplier be replaced at the factory.
