SIFT-MS selected ion flow tube mass spectrometry

Summary

  • Selected ion flow tube mass spectrometry is a sensitive and quantitative mass spectrometry technique for trace gas analyses using chemical ionisation of sample trace gases by selected positive ions during a well-defined time period along a flow tube. Absolute concentrations of trace compounds in humid air or breath are calculated in real time from the reagent and product ion signal ratios without the need for calibration using standards.
