Accurate Analysis of PFOA, PFHxS, and PFOS in Drinking Water Using a Triple Quadrupole LC/MS/MS

User Benefits

-PFOA, PFOS, and PFHxSconcentrations at 0.2 ng/L (concentration in water sample) can be quantitated using an optimized analytical conditions. -The LCMS-8050RX is equipped with CoreSpray technology, which improves consistency and reliability, so concentrations in drinking water can be quantitated with excellent recovery rates and repeatability for recovery tests (1 ng/L in samples).

Introduction

Perfluorooctanoic acid (PFOA), perfluorohexanesulfonic acid PFHxS), and perfluorooctanesulfonic acid (PFOS) are types of organofluorine compounds that are used for a wide range of applications, such as water repellents, waterproof materials, and surfactants. Due to their chemical stability, there is concern that their environmental persistence could result in harmful accumulations in humans. Therefore, PFOA and PFOS are included in the water quality management goal items, and PFHxS is listed as an item for consideration in Japan. This article describes the results from analyzing PFOA, PFOS, and PFHxS in drinking water that have been concentrated by a factor of 1000 based on the testing method of the water quality management in Japan.
