Optimization of PFAS analysis in fish tissue samples through a simplified and automated sample preparation workflow

Learn how to simplify sample preparation workflows by eliminating manual transfer steps.

By viewing this presentation, you will learn:

  • How to simplify your lab's sample preparation workflows by eliminating manual transfer steps when processing samples for PFAS analysis.
  • Tips for optimizing sample preparation and analytical performance to make sample analysis easier, more accurate, and more reliable.

Presentation Overview

Per-and polyfluoroalkyl substance (PFAS) testing has evolved rapidly in the past decade due to the severe health risks related to human exposure. As we expand our understanding of the prevalence of these toxic compounds, analytical laboratories must develop workflows to handle more challenging matrices. This presentation demonstrates a homogenization, extraction, and concentration workflow that provides exceptional precision, accuracy, and detection limits for PFAS in fish tissue samples. In addition, we discuss how to overcome some of the challenges associated with PFAS extraction and determination by isotope dilution or extracted internal standard quantification. Through this collaborative effort, we are thrilled to introduce a new simplified and automated sample preparation workflow applicable to testing for PFAS in solid samples.

Who Should View:

  • Analytical laboratories performing PFAS analysis
  • Laboratories testing tissue, soils, and biosolid samples
  • Sample preparation, extraction, and analytical chemists
  • Laboratories performing liquid chromatography-mass spectrometry (LC-MS/MS)
