When cleaning internal components it is important to maintain the quality of the
surface finish. Deep scratches or pits can cause loss of performance. Where no specific
cleaning procedure is provided, you should use fine abrasives to remove dirt from
metal components. Recommended abrasives are:
• 6000 Grade Micro Mesh (Part No. N9303420).
• 8000 Grade Micro Mesh (Part No. N9303421).

After cleaning with abrasives, it is necessary to wash all metal components in suitable
solvents to remove all traces of grease, oil and, if micro-mesh is used, rubber. The
recommended procedure is to swill or sonicate the components in a clean beaker of
methanol for at least ten minutes and subsequently to blot them dry with lint-free
tissue. Recommended solvents are:
After the components are reassembled, they should be blown with oil-free nitrogen to
remove dust particles.

To prevent contamination of the mass spectrometer, always wear clean,
lint-free, powder-free nitrile , nylon, or PVC gloves before touching,
removing or replacing parts. Hold the source by its handle only. Never
touch these parts with ungloved (bare) fingers, as this will introduce
contaminants into the system.
