8. Baking
The Microvision2
electronics package must not be exposed to ambient temperatures above 40
o
C. If the
analyser flange temperature exceeds 200
o
C the Microvision2 or Thermal Extender must be removed.
If baking at the maximum temperature of 200
o
C for 8 hours, the Microvision2 can remain attached to the
analyser, if baking for longer periods then a Thermal Extender must be used.
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.
The quadrupole can be run in Faraday mode at temperatures up to 200
o
C and to a maximum of 150
o
C
when using the multiplier at pressures better than 1e-8mbar. If this pressure is not attainable, then the
maximum temperature when using the multiplier is reduced to 90
o
C.
Serious damage to the multiplier will occur if it is used outside these parameters.
