Air is a dynamic matrix and is complex at trace levels. Conventional analytical technologies – such as gas chromatography mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC) – lack the time resolution and responsiveness of analysis required to provide timely answers, so that the root cause of air quality perturbations can be rapidly identified and addressed.
Selected ion flow tube mass spectrometry (SIFT- MS) is a revolutionary direct mass spectrometric technology for continuous, sensitive, selective, and robust analysis of air. Diverse VOCs (such as benzene and formaldehyde) and inorganic gases (such as sulfur dioxide and hydrogen sulfide) are detected in a single, simple analysis.
This webinar will present a variety of SIFT-MS based environmental applications, including:
A case study from China compared air quality monitoring data from gas chromatography with flame ionization detection (GC- FID) and SIFT-MS.
Marvin Shaw, Ph.D.
NCAS Research Scientist

University of York, UK
Marvin’s primary research interest is in urban air quality and the identification of primary emission sources of gas phase air pollutants (such as volatile organic compounds – VOCs) in urban areas, with the aim of understanding how and where these pollutants are emitted from and how this relates to estimates from national and regional emission inventories. I am an expert in the direct determination of VOC emissions using real-time chemical ionization mass spectrometry (PTR-MS, SIFT-MS) coupled with meteorological measurements through eddy covariance. Previous studies have involved deployment on both at ground sites and airborne platforms.

Vaughan joined Syft in 2002 after completing his Ph.D. in Physical Chemistry at the University of Canterbury, and post-doctoral fellowships at the Universities of Geneva, Western Australia, and Canterbury. With an extensive background in diverse applications of SIFT-MS (including 17 peer-reviewed publications and numerous conference papers), he now spearheads Syft’s global marketing efforts.
