Discover industry leading mass resolution, stability, and accurate/precise quantification of components in gas mixtures by using Thermo Scientific™ Ultra™ 271 QGMS. This double-focusing, multicollector gas source quantitative MS has guaranteed mass resolution of 10,000 (10 % valley definition) and mass resolving power of 30,000 (5 %, 95 % edge definition), allowing for the separation of target molecules from isobaric interferences both present in the sample mixture and arising from contaminants, adducts, and isotopologues.
