Recent developments and applications of selected ion flow tube mass spectrometry (SIFT-MS). [PDF]
Mass Spectrom Rev, 2023 AbstractSelected ion flow tube mass spectrometry (SIFT‐MS) is now recognized as the most versatile analytical technique for the identification and quantification of trace gases down to the parts‐per‐trillion by volume, pptv, range. This statement is supported by the wide reach of its applications, from real‐time analysis, obviating sample collection of

Journal of the American Society for Mass Spectrometry, 2023 Selected-ion-flow-tube-mass-spectrometry (SIFT-MS) is an analytical technique for volatile detection and quantification. SIFT-MS can be applied in a ‘white box’ approach, measuring concentrations of target compounds, or as a ‘black box’ fingerprinting technique, scanning all product ions during a full scan.

Aldehydes gas ozonation monitoring: Interest of SIFT/MS versus GC/FID [PDF]
Chemosphere, 2019 Two analytical techniques - online Gas Chromatography coupled with Flame Ionization Detector (often used method for VOCs monitoring) versus Selected Ion Flow Tube coupled with Mass Spectrometry (a more recent technique based on direct mass spectrometry) - were compared in association to an ozone-based gas treatment.

Increase of methanol in exhaled breath quantified by SIFT-MS following aspartame ingestion [PDF]
Journal of Breath Research, 2015 Aspartame, methyl-L-α-aspartyl-L-phenylalaninate, is used worldwide as a sweetener in foods and drinks and is considered to be safe at an acceptable daily intake (ADI) of 40 mg per kg of body weight. This compound is completely hydrolyzed in the gastrointestinal tract to aspartic acid, phenylalanine and methanol, each being toxic at high levels.
