ADVANCES IN SELECTED ION FLOW-DRIFT TUBE MASS SPECTROMETRY, SIFDT-MS, FOR AMBIENT QUANTIFICATION OF TRACE VOLATILE COMPOUNDS IN AIR

摘要

The Selected Ion Flow-Drift Tube Mass Spectrometry, SIFDT-MS, technique represents an important development of the Selected Ion Flow Tube Mass Spectrometry, SIFT-MS, technique building on its strengths (rapid switching between reagent ions and near thermal ion chemistry) and removing some of its weaknesses (lower sensitivity in comparison with proton transfer reaction, PTR, MS). It has a range of applications in biological, medical and environmental fields.
