5.2 Principle of Operation
There are always volatile hydrocarbon compounds
1
in the specimen chamber. These com-
pounds deposit on the specimen surface
2
. The specimen becomes contaminated. This may
influence the image quality.
1
2
The temperature of the cooling plate
3
decreases and the hydrocarbons change their physical
state, from volatile to solid. The compounds are deposited at the cooling plate. The cold surface
of the cooling plate acts as a trap for hydrocarbons and hence decreases the risk of contamina-
tion.
