Eliminating matrix effects: LC–MS analysis of biological fluids

Yelena Sapozhnikova from the United States Department of Agriculture spoke to The Column about her innovative research investigating PFAS in plastic food storage bags using targeted and non-targeted liquid chromatography–tandem mass spectrometry.

U.S. Environmental Protection Agency (EPA) Method 1633 signifies a pivotal shift in per- and polyfluoroalkyl substance (PFAS) determination, extending beyond drinking water.

Researchers propose a suite of batch effect removal neural networks in large liquid chromatography-mass spectrometry experiments to maximize sample classification performance between conditions.

The 72nd American Society for Mass Spectrometry Conference on Mass Spectrometry and Allied Topics will take place 2–6 June 2024 in Anaheim, California.
