Advances in On-line Absolute Trace Gas Analysis by SIFT-MS

Original language description

The basic physics and ion chemistry involved in the application of selected ion flow tube mass spectrometry, SIFT-MS, to accurate quantification of concentrations of trace gases in air and breath is now well understood. Algorithms, documented in previously published literature and based on a detailed understanding of the reactions of reagent ions with analyte molecules in the presence of larger concentrations of water vapour, carbon dioxide, nitrogen and oxygen molecules, are implemented in the instrument software that allow absolute real time analyses at the parts-per-billion by volume, ppbv, level, analyses made more robust by accounting for differential diffusion of the reagent and product ions along the reactor flow tube and mass discrimination inthe analytical quadrupole mass spectrometer. In the present article, other important details of this analytical method are discussed for the first time, including the choice of an optimum sample flow rate and the acquisition times of reag
