Abstract

A double quadrupole arrangement to remove polyatomic ions by collisions with an added target gas has been evaluated. The ions Ar2+, ArO+, and ArN+ were attenuated by factors of 50–400 to count rates of ≤100 counts s−1. Fifty to seventy percent of the analyte ions were retained. Removal of polyatomic ions and retention of analyte ions were favored by low-energy collisions with Xe or CH4 rather than typical target gases like N2 or Ar. Products of ion-molecule reactions between background ions and target gas in the first quadrupole could be observed.
