Ultrasonically Cleaning The Inner Source Components - Waters GCT Premier Operator's Manual

Where no specific cleaning procedure is given, fine abrasives should be used to
remove dirt from metal components. Recommended abrasives are:
• 1200-grade wet/dry paper.
• Lapping paper (produced by 3M®).
• Polaris powder.
After cleaning with abrasives, wash all metal components in suitable solvents
to remove all traces of grease and oil. Then ultra sonically clean the
components in a clean beaker of solvent and subsequently to blot them dry
with lint-free tissue:
• Propan-2-ol, [isopropyl alcohol (IPA)]
• Methanol
• Acetone
• Dichloromethane
Following reassembly, components should be blown with oil-free nitrogen or
dried in an oven to remove dust particles.

powder-free gloves at all times while handling the components.
Caution:
must not be cleaned in the ultrasonic bath.
To ultrasonically clean the inner source components:
