Analysis of Per- and Polyfluoroalkyl Substances (PFAS) in Drinking Water in Accordance with EPA 533

User Benefits

- The LC/MS/MS Method Package for PFAS in Drinking Water eliminates the need to configure analytical condition settings because it includes a ready-to-use method file in accordance with EPA Method 533. - The LCMS-8060RX can accurately measure PFAS in spike-and-recovery tests at concentrations as low as one-fourth of EPA’s Final MCLs.

Introduction

Per- and polyfluoroalkyl substances (PFAS) are widely used in various field and indistries. But their structural stability and resistance to decomposition means they easily accumulate in the environment, and are suspected of being harmful to humans. Therefore, the U.S. Environmental Protection Agency (EPA) and the European Chemicals Agency (ECHA) have been implementing measures to strengthen PFAS-related regulations in recent years. In abril 2024, the EPA announced final maximum contaminant levels (final MCLs). So it is important to use techniques capable of analyzing final MCLs of PFAS compounds with high sensitivity and accuracy. This article describes the overall process, from sample preparation to measurement, and results from analyzing 25 target PFAS compounds in drinking water based on EPA method 533. Good results were obtained from using the LCMS-8060RX system with the LC/MS/MS Method Package for PFAS in Drinking Water for spike-and-recovery tests in ultrapure water and drinking water.
