 To clean the tube lens and skimmer
Note Wear clean gloves when you handle the tube lens and skimmer.
CAUTION Do not clean the tube lens or skimmer with detergents, acidic or caustic
substances, or abrasives.
The sharp edge of the skimmer cone is fragile and any deformation might result in a loss
of efficient ion transmission. Use care not to drop the skimmer when cleaning it. Sonicate
the skimmer alone with the cone side up.
Sonicate the tube lens and skimmer alone in organic or aqueous solution. For most cleaning
applications, HPLC-grade methanol is the solvent of choice. However, use of buffers or salt
solutions might require that you use an aqueous solution. If you need to use a solvent other
than methanol, after cleaning the component, flush the component with distilled water and
then flush it with methanol as a final wash. You can air dry the skimmer and tube lens or blow
dry them with nitrogen gas. In all cases, ensure that all solvent has evaporated from the
components before reassembly.
