The 11th International Symposium on Recent Advances in Food Analysis will be in Prague, Czech Republic from 5–8 November 2024.

Per- and polyfluoralkyl substances (PFAS) are found in our food. Sensitive, precise, and accurate analytical methods are needed to estimate human exposure to these chemicals. A comparative study was performed between two extraction and cleanup methods (solid-phase extraction [SPE] and dispersive SPE) for the analysis of PFAS in apples. Both methods showed excellent sensitivity, precision, and accuracy. dSPE has some benefits over conventional SPE, and vice versa. The advantages and disadvantages of both methods are discussed.

LCGC Europe spoke to Stefan Van Leeuwen and Bjorn Berendsen from Wageningen Food Safety Research, The Netherlands, about a novel non-targeted approach to analyze PFASs using LC–HRMS with fragment ion flagging (FIF).

LCGC Europe interviewed Stefan van Leeuwen from Wageningen Food Safety Research (WFSR), in Wageningen, The Netherlands, on his novel multi-analyte approach to investigate bisphenol A (BPA), bisphenol A diglycidyl ether (BADGE), and their analogues using liquid chromatography–electrospray ionization tandem mass spectrometry (LC–ESI-MS/MS).
