Detecting PFAS can feel like finding a needle in a haystack, especially in those complex matrices. In my last project, we used a combination of solid-phase extraction and high-resolution mass spectrometry, which really helped pinpoint the contaminants. It’s a hassle, but once you nail down your method, it can save a lot of time in the long run! @HydroTech has some great resources on testing techniques if you need a refresher.
