We have witnessed incredible advances in the field of PFAS analysis, enabling scientists to more effectively detect even trace amounts and improving our ability to mitigate their negative impact.
Per- and polyfluoroalkyl substances (PFAS) are a group of human-made chemicals used in various industrial and consumer applications including cleaning products, personal care products, non-stick cookware, water-resistant fabrics, and fire-fighting foams. They have gained significant attention in recent years due to their global presence in water sources, soil, air, wildlife, and human populations, and potential ecological and health risks. With more evidence about the harmful effects of PFAS continuing to emerge, regulatory agencies and public health organizations have been spurred on to increase monitoring of PFAS contamination.
Here, we explore the most exciting recent developments in the field of PFAS analysis including advancements in analytical techniques using high-tech liquid chromatography-tandem mass spectrometry (LC-MS/MS) technology, robust sample preparation methods, the challenges, best practices, and global implications of PFAS testing and future directions in the field.
Clinical research analysis of PFAS in human serum by LC-MS/MS using Captiva EMR-Lipid cleanup
Efficient sample preparation is essential for clinical laboratories conducting analysis of PFAS in human serum using LC-MS/MS because phospholipids (PPLs), a type of molecule found in serum, can introduce undesired matrix effects. These interferences can lead to inaccurate measurements and affect the sensitivity and specificity of the analysis. By implementing appropriate sample preparation steps to remove or minimize the presence of phospholipids, research laboratories can improve the reliability and accuracy of their studies.
Watch this webinar to learn how to conduct effective serum sample preparation and LC-MS/MS analysis of PFAS using protein precipitation followed by PPL removal with the Captiva EMR-Lipid cartridges from Agilent Technologies. Plus, read the highlights from the Q&A discussion.
Comparison of PFAS recoveries between cartridge format WAX/GCB vs dispersive GCB
PFAS pose significant environmental concerns due to their toxicity, widespread dispersion, and persistence, which has disastrous negative impacts on aquatic ecosystems. To accurately monitor and assess the presence and levels of PFASs in environmental water samples, robust and precise sample preparation techniques are crucial to minimize interferences from other compounds and ensure that the measured concentrations reflect the true levels of PFAS contamination. This involves extracting and purifying target analytes from complex environmental matrices, which can be challenging because PFAS are often in low concentrations and present in complex sample matrices.
