A practical and robust method for quantification of long-chain PFAS in food matrices using 18O-water-based generation of internal standards and LC-ESI-MS/MS.
Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are persistent organic contaminants of global concern. In response to increasingly stringent international regulations, including the addition of long-chain perfluoroalkyl carboxylic acids (LC-PFCA) to the Stockholm Convention in 2025, accurate monitoring of these co...
