4. Grasp the ridges on either side of the ion source interface with your fingers and carefully
pull it out of the vacuum manifold

5. Place the ion source interface on the clean, lint-free work surface.
Chemicals accumulating on the surfaces of the skimmer and tube lens form an insulating layer
that can modify the electrical fields controlling ion transmission. The skimmer and tube lens
require cleaning less often than the ion sweep cone and the ion transfer tube. No tools are
needed to remove or install these components.
CAUTION Do not scratch the outside of the skimmer cone.
To clean the skimmer and tube lens, follow these procedures:
1. To remove and clean the tube lens and skimmer
2. To reinstall the tube lens and
