Selected Ion Flow Tube Mass Spectrometry for On-Line Trace Gas Analysis in Biology and Medicine
European Journal of Mass Spectrometry, 2007Selected ion flow tube mass spectrometry, (SIFT-MS), is a technique for simultaneous real-time quantification of several trace gases in air and exhaled breath. It relies on chemical ionization of the trace gas molecules in air/breath samples introduced into helium carrier gas, using H 3 O

Selected ion flow tube mass spectrometry
2020Selected ion flow tube mass spectrometry (SIFT-MS) was first realized as a viable technique for the analysis of trace gases in ambient air in 1996 and its potential for direct online, real-time analysis became immediately obvious. Instrumental development has gone through several phases from a large laboratory-based device to the current mobile ...

Selected ion flow tube mass spectrometry of urine headspace
Rapid Communications in Mass Spectrometry, 1999We describe the use of our selected ion flow tube mass spectrometric technique (SIFT-MS) for the analysis of the headspace above urine. Ammonia, nitric oxide, acetone, ethanol and methanol are identified as the dominant species. As expected, the ammonia is increased in the headspace by making the urine alkaline and the nitric oxide is increased by ...

Reactions of Ions with Ionic Liquid Vapors by Selected-Ion Flow Tube Mass Spectrometry
The Journal of Physical Chemistry Letters, 2011Room-temperature ionic liquids exert vanishingly small vapor pressures under ambient conditions. Under reduced pressure, certain ionic liquids have demonstrated volatility, and they are thought to vaporize as intact cation-anion ion pairs. However, ion pair vapors are difficult to detect because their concentration is extremely low under these ...

Selected ion flow tube mass spectrometry of exhaled breath condensate headspace
Rapid Communications in Mass Spectrometry, 2008Abstract Collection of exhaled breath condensate (EBC) is a relatively simple noninvasive method of breath analysis; however, no data have been reported that would relate concentration of volatile compounds in EBC to their gaseous concentrations in exhaled air.

Quantification of Methanol in the Presence of Ethanol by Selected Ion Flow Tube Mass Spectrometry
European Journal of Mass Spectrometry, 2016The quantification of trace compounds in alcoholic beverages is a useful means to both investigate the chemical basis of beverage fLavor and to facilitate quality control during the production process. One compound of interest is methanol which, due to it being toxic, must not exceed regulatory limits.

Quantification of hydrogen cyanide in humid air by selected ion flow tube mass spectrometry
Rapid Communications in Mass Spectrometry, 2004Abstract Following our recent observation that Pseudomonas bacteria in vitro emit hydrogen cyanide, we have found it necessary to investigate the ion chemistry of this compound and to extend the kinetics database for selected ion flow ...

Application of selected ion flow tube mass spectrometry to real‐time atmospheric monitoring
Rapid Communications in Mass Spectrometry, 2010Abstract Data are presented for real‐time atmospheric monitoring of volatile organic chemicals (VOCs) in air using selected ion flow tube mass spectrometry (SIFT‐MS) technology. These measurements were made by one of the new generation of SIFT‐MS instruments.
