SIFT-MS utilises direct, soft chemical ionisation coupled with mass spectrometric detection, rather than chromatographic separation, to analyse samples with high specificity. This means that SIFT-MS data differ significantly from GC and LC data in that they are a superposition of mass spectra of the different reactive compounds (analytes and matrix ...

SIFT-MS Measurement of VOC Distribution Coefficients in Human Blood Constituents and Urine
Applied Occupational and Environmental Hygiene, 2003The new technique of selected ion flow tube-mass spectrometry (SIFT-MS) has been applied to the measurement of Henry's Law constants for the volatile organic chemicals o-xylene and trichloroethylene that both have low solubility in aqueous solvents. The method is validated by measurements in water at 298 K using the equilibrium partitioning in closed ...

The Principles of the SIFT-MS Technique
The selected ion flow tube mass spectrometry (SIFT-MS) technique operates on very different principles to the more established chromatographic methods. This chapter provides a comprehensive introduction to how SIFT-MS instruments work, the ion–molecule reaction (IMR) chemistry that provides both comprehensive and specific analysis, and the utilisation ...openaire +1 more source
Medical applications of SIFT-MS in New Zealand
2008Selected ion flow tube mass spectrometry (SIFT-MS) is arelatively new analytical technique which offers real time identification and quantification of trace gases.It has the ability to detect and quantify the volatile organic compounds(VOCs) in various media such as liquid headspace and breath, thus opening up many new opportunities in medical research.

Integrity of Storage Media for Clinical Applications with SIFT-MS Instruments
2006Tedlar™ bags are a promising medium for remote breath collection and later analysis using SIFT-MS for disease diagnosis. It is important to understand the changes in integrity of samples stored in Tedlar™ bags. However, there is little work into this problem completed to date, and thus little known about these issues.

Modifying an Existing SIFT-MS Method (Procedure 7)
SIFT-MS, with its chromatography-free, soft chemical ionisation approach to the analysis of volatile compounds requires different procedures for modifying validated test methods compared to GC. This chapter provides procedures for modifying SIFT-MS methods involving addition or removal of analytes, modification to product ion selections, a change of ...openaire +1 more source
