2. Safety summary
2.1. Intended use
The Plasma Cleaner Add On is used to generate reactive gas-phase radicals in a plasma. This
plasma is fully contained in the Plasma Cleaner unit. The radicals migrate into the specimen
chamber and chemically react with unwanted hydrocarbons.
This is useful for:
•Fast specimen decontamination 
Decontamination time can be adjusted to fit the customer needs. Typically, 2-5 minutes to
clean the sample, or 10-30 minutes runs for in-depth decontamination of stage and chamber.
•Safe decontamination
It is completely safe for the equipment.
•Improved image quality
Contamination compromises achievable image resolution.
•Improved measurement accuracy
Sample features can be measured accurately.
