Robustness Evaluation of PFAS Analysis in Soil Using LCMS-8060RX

User Benefits

- The LCMS RX series, which improved stability and robustness with CoreSpray technology, showed excellent peak area repeatability when measuring PFAS at low concentrations 500 consecutive times in a soil matrix. - Quality control samples measured for every 20 soil sample also showed good recovery rates of all PFAS remaining between 80 and 120 %.

Introduction

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are widely used in various field and indistries. But their tendency to accumulate in the environment due to their highly stable structures, which resist degradation, raises concerns about their effects on humans. Therefore, the Environment Protection Agency (EPA) in the USA and the European Chemicals Agency (ECHA) have recently strengthened regulations on PFAS. Research has shown they accumulate in the bodies of humans from drinking water and in livestock, agricultural, and marine products from water and soil and that they may have a potential adverse effect on health. This has created a need for highly accurate and reliable methods of measuring PFAS in not only water but also in soil and other samples with relatively complex matrixes. This article presents a robustness study that added 30 PFAS to a soil matrix and used the LCMS-8060RX to measure these PFAS in the soil matrix 500 consecutive times. The LCMS-8060RX produced good results and provided a robust analytical platform for the measurement of low concentrations of PFAS in a soil matrix sample.
