Abstract Selected ion-flow tube mass spectrometry, SIFT-MS, relies on chemical ionization of trace gases in air and breath samples using precursor ions that can be rapidly changed to allow the analysis of transient or limited-volume samples. The precursor ion species of choice are H 3 O + , NO + and O 2 + because they do not react with the major components of air. In this article, we present the results of a study designed to investigate if consistent quantification of chemically different… CONTINUE READING
