Attenuation of Polyatomic Ion Interferences in Inductively Coupled Plasma Mass Spectrometry by Gas-Phase Collisions

Abstract

A double quadrupole arrangement to remove polyatomic ions by collisions with an added target gas has been evaluated. The ions Ar<sub>2</sub><sup>+</sup>, ArO<sup>+</sup>, and ArN<sup>+</sup> were attenuated by factors of 50-400 to count rates of \lesssim 100 counts s<sup>−1</sup>. 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 CH<sub>4</sub> rather than typical target gases like N<sub>2</sub> or Ar. Products of ion-molecule reactions between background ions and target gas in the first quadrupole could be observed.
