Forever Chemicals: Liquid Chromatography for PFAS Detection

Methods and workflows for overcoming the challenges of PFAS analysis 

Liquid chromatography coupled to mass spectrometry (LC-MS) is the most widely used method to detect per- and polyfluoroalkyl substances (PFAS) in drinking water. As the need for PFAS analysis expands beyond water samples to include soil, tissues, and more, robust methods and workflows are needed to ensure accurate and reliable data. 

Forever Chemicals: Liquid Chromatography for PFAS Detection

PFAS pose unique challenges for analysis. Often present in trace amounts, they require the high degree of sensitivity and low detection limits offered by LC/MS analysis for accurate detection. Contamination is a pervasive concern, as they can persist in LC instruments, consumables, and other laboratory items. Complex matrices, especially those contained in environmental samples like soil and wastewater, can also interfere with analysis. 

In 2019 the Environmental Protection Agency (EPA) released a solid-phase extraction (SPE) LC-MS/MS method for testing PFAS in drinking water. Since then, new methods have been released for analyzing PFAS in a wide range of sample matrices, including soil, groundwater, and biological tissue, among others. These standardized approaches address many challenges associated with PFAS testing.
