Quantitative Analysis of PFAS in Drinking Water Using Liquid Chromatography Tandem Mass Spectrometry
Per- and polyfluoroalkyl substances (PFAS) are chemicals found in fire‑fighting foams and consumer products requiring water-resistant and stain-repellent properties. As a result of their unique chemical properties and long‑term widespread usage, these chemicals are an emerging human health concern. US Environmental Protection Agency (EPA) released analytical methods for PFAS measurement in 2009 and most recently in November of 2018. In this article, data generated using these methods with allowed analytical modifications is presented and demonstrates robustness and reproducibility while achieving low level detection limits in drinking water.
