SIFT-MS instruments are readily deployed for ambient air monitoring – whether for short-term campaigns or in permanent installations.

Vaughan Langford Syft Technologies Director - Applications & Marketing

Dr. Vaughan Langford

BSc(Hons), PhD

Principal Scientist / Consultant

Vaughan joined Syft in 2002 after completing his PhD in Physical Chemistry at the University of Canterbury (1997) and post-doctoral fellowships at the Universities of Geneva, Western Australia, and Canterbury.

As manager of Syft’s contract laboratory, Vaughan has worked extensively with customers to understand their analysis needs and develop market-tested SIFT-MS solutions.

Vaughan has experience across all SIFT-MS application areas, but has particular expertise in environmental and food industry applications. He is an expert in SIFT-MS application and method development.

In addition to the technical aspects of his role, Vaughan attends and presents on many of Syft’s webinars and attends various conferences on our behalf.

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
National Centre for Atmospheric Science
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.
