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.
