Simultaneous Analysis of 40 PFAS Components in Drinking Water Using a Triple Quadrupole LC/MS/MS

User Benefits

-Enables analysis of 40 PFAS components within 20 minutes and simultaneous analysis of multiple components without sensitivity loss. -Enables quantitative analysis of concentrations as low as 0.2 ng/L (in water samples) for PFOA, PFOS, PFHxS, and others. -Consistent and accurate results can be obtained with good recovery rates and reproducibility data for recovery tests.

Introduction

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) offer broad versatility for a wide range of applications. Due to their structural stability and resistance to decomposition, they easily accumulate in the environment and are suspected to be harmful for humans. Due to concerns about their environmental impacts, 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. Consequently, efforts to comply with such PFAS regulations have been increasing every year, and the list of compounds governed by such regulations continues to grow. That makes it increasingly useful to apply an analytical method that can reliably analyze all the various PFAS substances at the same time. This article describes the results from simultaneously analyzing 40 PFAS components (Table 1) as target compounds after automatic sample preparation. Good results were obtained from measuring standard solutions and recovery tests of drinking water samples.
