Detection of PFAS in Aqueous Samples by Matrix Assisted Laser Desorption Ionisation Time-of-Flight (MALDI-TOF) Mass Spectrometry

User Benefits

- Obtain results indicative of PFAS in aqueous samples within minutes for further study. - Minimal sample preparation required prior to acquisition. - Method can be applied to numerous sample types following additional preparation.

Introduction

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants which accumulate in water, soil and living organisms. PFAS negatively impact human health with links to cancer, immune system depression and hormone disruption, amongst others, already being established. Worldwide, concern regarding the exposure of biological organisms to environmental PFAS continues to grow. PFAS contamination in water is a particular focus for both regulations and research. Widespread water contamination has been reported, and removal continues to be difficult and expensive. We developed a simple, cost-effective method for the detection of PFAS in aqueous samples using an entry-level benchtop linear MALDI-TOF mass spectrometer.
