SIFT-MS optimization for atmospheric trace gas measurements at varying humidity [PDF]

Atmospheric Measurement Techniques, 2020
As direct real-time analysis techniques, selective ion flow tube mass spectrometry (SIFT-MS) and proton-transfer reaction mass spectrometry (PTR-MS) provide online measurement of volatile organic compounds (VOCs).

Source apportionment and quantification of liquid and headspace leaks from closed system drug-transfer devices via Selected Ion Flow Tube Mass Spectrometry (SIFT-MS) [PDF]

PLoS ONE, 2021
A system to differentiate and quantify liquid and headspace vapor leaks from closed system drug-transfer devices (CSTDs) is presented. CSTDs are designed to reduce or eliminate hazardous drug (HD) exposure risk when compounding and administering HDs ...

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

Comparison of Untargeted and Markers Analysis of Volatile Organic Compounds with SIFT-MS and SPME-GC-MS to Assess Tea Traceability [PDF]

Foods
Tea is one of the most consumed beverages in the world and presents a great aromatic diversity depending on the origin of the production and the transformation process. Volatile organic compounds (VOCs) greatly contribute to the sensory perception of tea

Simultaneous Real-Time Measurement of Isoprene and 2-Methyl-3-Buten-2-ol Emissions From Trees Using SIFT-MS [PDF]

Frontiers in Plant Science, 2020
The C5 hemiterpenes isoprene and 2-methyl-3-buten-2-ol (MBO) are important biogenic volatiles emitted from terrestrial vegetation. Isoprene is emitted from many plant groups, especially trees such as Populus, while emission of MBO is restricted to ...

Prediction and detection of human epileptic seizures based on SIFT-MS chemometric data. [PDF]

Sci Rep, 2020
AbstractAlthough epilepsy is considered a public health issue, the burden imposed by the unpredictability of seizures is mainly borne by the patients. Predicting seizures based on electroencephalography has had mixed success, and the idiosyncratic character of epilepsy makes a single method of detection or prediction for all patients almost impossible.

Measurement of Odorants in Livestock Buildings: SIFT-MS and TD-GC-MS

Chemical Engineering Transactions, 2012
Air samples from animal farming are analysed in parallel using traditional TD-GC-MS (thermal desorption gas chromatography mass spectrometry) and SIFT-MS (selected ion flow tube mass spectrometry).

SIFT-MS for Livestock Emission Characterization: Application of Similarity Coefficients

Chemical Engineering Transactions, 2012
SIFT-MS (selected ion flow tube mass spectrometry) is used to construct libraries for emissions from pig and broiler farming activities. Libraries are based on full mass scans in m/z range 15 to 250 using HO+, NO+ and O2 precursor ions.
