Episode 20: Uncovering PFAS Challenges: Forever Chemicals in Labs with Edward Faden of MAC-MOD

Join David Oliva on the Concentrating on Chromatography podcast as he interviews Edward Faden, Vice President and co-owner of MAC-MOD Analytical, a leading provider of chromatography solutions since 1986. In this insightful discussion, Edward shares the history and expertise of MAC-MOD, based in Chadds Ford, Pennsylvania, and dives deep into the critical challenges of analyzing PFAS (per- and polyfluoroalkyl substances), often called "forever chemicals."Key topics include:- The pervasive nature of PFAS contamination in both environmental and laboratory settings.- Surprising sources of PFAS contamination identified in standard lab setups, from gas line tubing to everyday consumables.- The essential role of the PFAS Delay Column in ensuring accurate analysis by minimizing background interference.- Best practices for labs starting PFAS analysis to reduce contamination risks from day one.- Exciting developments in rapid sample pre-screening methods to prevent cross-contamination.Edward also discusses why PFAS are so widespread—used in products like non-stick cookware and waterproof clothing since the 1940s—and the ongoing struggle to manage their environmental persistence. Whether you're a chemist, environmental scientist, or simply curious about the impact of forever chemicals, this conversation offers valuable insights into cutting-edge analytical solutions.Don't miss out on learning about MAC-MOD's innovative approaches and future plans for PFAS analysis.
