Event Overview:

The analysis of PFAS compounds typically requires the use of LC-MS/MS systems. However, as more PFAS compounds are discovered and more complex matrices are tested, both regulated and unregulated analytical methods will need to adapt. In this webinar, we will show the benefits of alternative workflows on the latest breakthroughs for adsorbable organic fluorine (AOF) and (and extractable organic fluorine (EOF) and how different sample-prep extraction (SPE) phases are used for determination of total PFAS. Additionally, we will discuss the modification of the stationary phases in single and dual configurations in one, which causes the sorption-elution characteristics of different classes of PFAS compounds to be altered. These topics will help laboratories in both regulated and unregulated environments adapt to the unique challenges PFAS analysis creates.

Key Learning Objectives:

  • Learn options for SPE phases for PFAS extraction from water and soil samples
  • Apply EOF and AOF methods to measure total organic fluorine in wastewater, surface waters, and air
  • Learn how total organic fluorine methods can give a more complete picture of PFAS in environmental samples

Who Should Attend:

  • Lab Managers and researchers involved in PFAS analysis.
  • PFAS analysts wanting to learn more about sample preparation for Combustion IC.
  • Lab managers and researchers interested in expanding their PFAS capabilities beyond just the currently regulated compounds
