No cluster ions visible
- Possible reason 1: Particles are lost before entering the instrument
Instrument inlet is not properly grounded or inlet tube is too long.

If the offset operating mode is not working correctly, wrong offset estimate is subtracted from ions or particles mode signal.
Solution Check if there are any diagnostic warnings shown for offset records. Check that
Possible reason 3: 9 V central electrode voltage is missing
