This study introduces an optimized LC-MS/MS methodology for the comprehensive analysis of Per- and Polyfluoroalkyl Substances (PFAS) in vegetable, fruit, and baby food. The method demonstrates an exceptionally low limit of quantification, reaching 0.0005 µg/kg for some compounds in matrix, while accurately detecting and quantifying the PFAS compounds listed in the Commission Recommendation (EU) 2022/1431. The combination of enhanced sensitivity of the Xevo™ TQ Absolute MS System, with the increased clean-up efficacy of a prototype bilayer dual-phase GCB/WAX SPE cartridge, gave excellent recoveries, between 87 and 116% for the mandatory PFAS, and between 65 and 131% for the majority of the recommended compounds along with repeatability (RSDr) ≤10%.
