Event Overview:

Known as “forever chemicals”, per- and polyfluoroalkyl substances (PFAS) are persistent synthetic chemicals that pose serious environmental and health risks, making accurate analysis essential. EPA Method 1633A outlines procedures for quantifying 40 PFAS in various complex matrices, but its manual solvent extraction process for solids is often labor-intensive and prone to variability. This webinar will explore the unique challenges of PFAS sample preparation and explore an automated solvent extraction system that utilizes the same sample sizes, solvents, volumes, and cycles as described in 1633A—delivering consistent, ready-to-analyze extracts that also meet the performance criteria of the method. Results from contaminated soil and tissue samples will be discussed. Attendees will also learn about the latest tools and protocols that streamline PFAS sample preparation and improve lab efficiency.


Key Learning Objectives:

  • Discover tips and tricks for better PFAS analysis
  • Learn about a simple automated option to meet EPA 1633A
  • Explore real-world samples, as well as spikes, to determine extraction efficiency

Who Should Attend:

  • QA and QC Lab Personnel
  • Lab Managers
  • Anyone facing challenges analyzing PFAS
