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.

Many modern industrial uses of specialty gases require very high purities to ensure that – among other reasons – yields are high, catalysts are not poisoned, and equipment is not damaged or subject to frequent maintenance.

In this web seminar, we introduce selected ion flow tube mass spectrometry (SIFT-MS), a form of direct mass spectrometry that provides real-time detection of a wide range of volatile organic compounds and many inorganic gases to sub-part-per-billion concentrations (by volume; ppbv). Applications of SIFT-MS to diverse process and specialty gas applications will be described, including:

Key Learning Objectives:

  1. The fundamentals of the SIFT-MS technique, including its operating principles and performance characteristics.
  2. Understanding how the diverse different chemical ionization mechanisms accessible using SIFT-MS enable trace impurities to be analyzed in diverse bulk gases.
  3. Insights into how SIFT-MS can be applied to diverse, challenging gas analysis challenges.

The strength of SIFT-MS is that it combines four factors that these other techniques are unable to combine:

  • Rapid analysis
  • Comprehensive compound detection, including highly reactive species
  • Selectivity, and
  • Simple, low-cost operation.
