The European Commission's regulation on maximum levels for certain contaminants in food highlights the need for precise and reliable methods to quantify per- and polyfluoroalkyl substances (PFAS) in various food matrices. This article discusses development and validation of a robust method for analyzing 21 PFAS compounds in chicken eggs using solid-phase extraction (SPE) and liquid chromatography–mass spectrometry (LC–MS).
Applying Sustainability Concepts to Modern Liquid Chromatography
June 4th 2024Governments are striving to implement policy changes towards a greater use of green technology, specifically around the generation of energy. Individuals and industrial organizations have also taken up the challenge, and now many companies are driving to significantly reduce their environmental footprint, or indeed become carbon negative within very short time frames.
PLS-DA With Univariate Filtration Refines Discovery of Untargeted Metabolomics Data Using LC–MS
June 3rd 2024As opposed to targeted metabolomics which looks only at a predetermined set of metabolites or their pathways, an untargeted approach was preferred by this research team because of its unbiased yet still comprehensive nature.
