Maintenance of the Lens System (LCMS)
Maintenance of the Lens System (LCMS)
Since the lens system focuses the ions generated by the ionization unit, it becomes soiled over long periods of use and the detection sensitivity diminishes. For this reason you must clean the following lens system components: Qarray, skimmer, and multipoles. Also, clean the lens system components when a considerable decrease in sensitivity is observed.

Answer
CAUTION: Do NOT disassemble either multipole body. Disassembling them could cause injuries and instrument failure.
1. Remove the two screws(1) and (3) and then remove lenses(2) and (4) from multipoles 1 and 2, respectively.

2. Wipe off any soiling on the lens inner surface using a wiper impregnated with methanol.

3. Immerse the multipoles and lenses in methanol and clean them by ultrasonic cleaning (for 10 to 30 minutes).
4. Remove the multipoles from the methanol and leave them to air until dry.
