Clean the Trap Components
To clean the ion trap parts, you will
•
Clean the stainless steel parts or clean the SilChrom-coated parts
•
Clean the quartz spacers
NOTE: For SilChrom-coated electrodes, Do Not use Aluminum Oxide.
Clean Stainless Steel Parts
To clean the filament endcap, RF voltage ring electrode, and exit endcap,
proceed as follows:
1. Using a slurry of number 600 aluminum oxide in water (or glycerol) and a
cotton-tipped applicator, remove all contaminants from the stainless steel ion
trap parts.
•
Use the wooden end of a cotton swab, cut at an angle, to clean the
inside corners, i.e., the holes in the endcaps.
•
Contaminants sometimes appear as dark or colored areas, but they may
also be invisible. Clean each part thoroughly, even if there is no
apparent contamination.
