How to optimise your PFAS air sampling method using thermal desorption

By viewing this on-demand webinar you will learn:

  • How to optimise thermal desorption for monitoring PFAS in stack gases, ambient and indoor air.
  • Which sampling techniques should be employed for different types of PFAS and breakdown products.
  • What are the challenges, and misconceptions, with sampling and analysis of PFAS in air and how to manage them.

Event overview

Research surrounding the health effects of per- and polyfluoroalkyl substances (PFAS) continues to grow, along with investigation of exposure pathways. PFAS in air are monitored globally, but recent regulatory changes have prompted a requirement for this to become routine. This has highlighted some challenges when performing PFAS monitoring at ultra-low concentration levels, including the need for pre-concentration of large volumes of air and for PFAS free blanks.

Thermal desorption (TD) has long been considered the gold-standard technique in environmental air monitoring for volatile organic compounds. The PFAS community is now turning to the technique for monitoring key species in air, and for undertaking research projects to understand the extent of the PFAS species present in the environment.

This presentation discusses the advantages that TD offers, how to optimise a system for targeted and untargeted PFAS analysis, and how to overcome challenges posed by low-level PFAS monitoring.

Why should you view it?

  • Users new to the topic of PFAS monitoring will increase understanding of the options available for sampling and analysis.
  • TD users will gain information on how instrumentation could be used for expanding monitoring activities.

Who should view it?

  • Researchers interested in PFAS
  • Laboratory and project managers working with PFAS
  • Analysts who want to monitor PFAS destruction efficiency
  • Environmental consultants
