To clean the durable components:
1. Remove contaminants from all the components you are cleaning.
a. Use a slurry of #600 aluminum oxide in glycerol on a cotton-tipped applicator to
clean each component. Contamination can be indicated by a dark or discolored area,
but it is often invisible. The heaviest contamination is usually found around the
apertures, such as the electron entrance hole of the ion volume.
Note Clean only the metal pieces of the repeller, lens 1 and lens 3/RF lens with
aluminum oxide.
b. Clean each component thoroughly, even if no contamination is visible. To clean
components faster, use a Dremel® tool and polishing swab at its lowest speed.
WARNING ELECTRICAL SHOCK HAZARD: Exposing the Dremel tool to
standing water may cause an electrical shock.
WARNING FIRE HAZARD: Using the Dremel tool near flammable vapors may
cause a fire.
c. Clean the crevices of a component using a non-metal tool. It is very important to
make sure you remove all of the debris or discoloration found in small edges of each
component, in particular the ion volume. Otherwise, the debris or discoloration
might affect the quality of your data.
d. If you are cleaning the CI ion volume, use a razor blade to sharpen the wooden end of
a wooden cotton swab to a 45° angle.
e. Twist the sharpened end of the swab into the electron entrance hole on the CI ion
volume to clean out debris. You may need to use several swabs before the electron
entrance hole is clear of debris.
