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.", pages = "976-980", url = "http://www.ingentaconnect.com/content/sas/sas/1989/00000043/00000006/art00011", doi = "doi:10.1366/0003702894204065", keyword = "Inductively coupled plasma-mass spectrometry, Polyatomic ion interferences, Tandem quadrupoles, Collision-induced dissociation, Ion molecular reactions" }
