Strategies for Total PFAS: Extractable vs. Adsorbable Organic Fluorine

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

Featured Speakers:

Dr. Richard Jack

Global Market Development Manager, Food & Environmental

Phenomenex

Richard has over 18 years of experience with chromatography and mass spectrometry for the environmental, food, cannabis, semiconductor, chemical, and pharmaceutical industries. He is a former EPA scientific advisor and has collaborated with global regulatory agencies to develop validated methods through new applications, instrumentation, column chemistries, and software. He is currently the second vice chairman for the ASTM D19 subcommittee on water analysis. He received his Ph.D. in biochemistry and anaerobic microbiology from Virginia Tech University in Blacksburg. He received his master’s in ecology from the University of Tennessee in Knoxville.

Dr. Susan Richardson

Arthur Sease Williams Professor of Chemistry

University of South Carolina

Dr. Susan Richardson is the Arthur Sease Williams professor of chemistry at the University of South Carolina and was formerly at the U.S. EPA for many years. Susan’s research surrounds the study of toxicologically important disinfection by-products in drinking water and, more recently, other emerging contaminants, including PFAS. Susan served the last two years as president of the American Society for Mass Spectrometry and is an associate editor for Environmental Science & Technology. She received the American Chemical Society (ACS) Award for Creative Advancements in Environmental Science & Technology (2008), an Honorary Doctorate from Cape Breton University (2006), an AAAS Fellow (2019), an ACS Fellow (2016), the Herty Medal (2020), the Southern Chemist Award (2020), the Walter J. Weber, Jr. AEESP Frontier in Research Award (2021), and the Analytical Scientist Power List (2021 and 2019). Susan has published >190 journal articles and book chapters and writes an invited biennial review for Analytical Chemistry, entitled “Water Analysis: Emerging Contaminants and Current Issues”. She has a Ph.D. in Chemistry from Emory University and a B.S. in Chemistry & Mathematics from Georgia College & State University.Email: richardson.susan@sc.edu
