6. Baking
The control electronics (e-Vision)
must not be exposed to temperatures above 40
o
C
and should be removed from the analyser during baking.
The analyser may be baked up to 250
o
C, but care should be taken to avoid
exposing the ceramic feedthrough to sudden changes in temperature.
CAUTION
The Electron Multiplier (SEM) MUST NOT be operated at
temperatures above 50
o
C.
With dual (faraday and electron multiplier) detector instruments, serious damage
will occur to the electron multiplier if operated at temperatures above 50
o
C.
In this case only the Faraday detector should be used, NOT the multiplier.
The multiplier will not be damaged by high temperatures, providing it is not
switched on.
