Analytical Considerations to Improve Regulated and Unregulated Analysis of PFAS Compounds

Key Learning Points:

• Explore how column choice affects PFAS selectivity

• Learn how modified C18, -Hexyl, Phenyl-Hexyl, and Fluorinated phases affect PFAS selectivity

• Understand how using organic modifiers can improve PFAS selectivity

Presenter: Karl Oetjen, PhD (Senior Scientist, SCIEX)

Karl Oetjen is a Senior Technical Marketing Scientist for Food, Environmental, Forensic, Clinical and Cannabis applications at SCIEX. Before joining SCIEX, he completed his PhD at Colorado School of Mines (Golden, Colorado) in Hydrologic Science and Engineering under Dr. Chris Higgins. Karl’s dissertation research focused on nontarget characterization of complex surfactant mixtures, including aqueous film forming foams. This work led to the discovery several novel per- and polyfluorinated alkyl substances (PFAS) that since have been found in variety of environmental samples and industrial chemicals. Since joining SCIEX, Karl has worked with numerous labs creating and implementing both regulated and unregulated quantitative and qualitative screening methods.
