Event Overview:

Over the last 40 years, thermal desorption with GC–MS has been widely used to analyse VOCs and SVOC in air and materials. Many laboratories around the world routinely use the technique, but analysts continue to be presented with new challenges.

This talk covers how conventional GC–MS capabilities can be extended to analyse new organic pollutants like microplastics, PFAS, trace contaminants and air toxics, hydrogen gas impurities and breath biomarkers, using an advanced portfolio of automated thermal desorbers. Also discussed are several application examples that deliver more sample productivity to the analytical laboratory, through minimised sample preparation and unattended operation.

Key Learning Objectives:

  • Familiarise yourselves with key and trending applications for environmental, clinical and material emission studies
  • See how multiple methods using different sample introduction techniques can be run on the same GC–MS without user intervention
  • Learn how to get the highest sensitivity for VOC & SVOC analysis, including from aging GC–MS systems, thanks to the inherent sample pre-concentration of thermal desorption
  • Discover how to maintain high-quality standards throughout your TD-GCMS analytical workflow

Who Should Attend:

  • Environmental chemists interested in the analysis of emerging contaminants like microplastics and PFAS
  • Analytical laboratory managers and associated staff running GC and GC–MS workflows.
  • Research scientists developing methods for the analysis of hydrogen fuel gas and its impurities
  • Analysts using thermal desorption as a technique for analysing VOCs & SVOCs for GC and GC–MS analysis
