New Approaches to PFAS Quali- and Quantification using GC-MS

  • Known as “forever chemicals”, per- and polyfluoroalkyl substances (PFAS) are a class of synthetically produced chemicals that includes an estimated 10.000 compounds. Due to the persistence, toxicity and ubiquitous occurrence, research has focused on the qualification and quantification of the most important compounds as well as on the investigation of toxicity and possible routes of entry over the last 10 years. Liquid chromatography - mass spectrometry (LC-MS) is the analytical standard to test for PFAS, as the spectrum of detectable compounds is significantly more comprehensive than it is currently the case with gas chromatography - mass spectrometry (GC-MS). However, to be able to test for PFAS contamination in a more process-independent manner and to make the analysis more widely accessible, methods based on GC-MS are currently being developed. Since GC-MS methods only cover a fraction of the compounds belonging to the PFAS group so far, further development of the correspondingKnown as “forever chemicals”, per- and polyfluoroalkyl substances (PFAS) are a class of synthetically produced chemicals that includes an estimated 10.000 compounds.

Since GC-MS methods only cover a fraction of the compounds belonging to the PFAS group so far, further development of the corresponding measurement methods is inevitable [1, 2]. The here described work is part of the EU project 23IND13 ScreenFood [3]. The aim is to develop sensitive analytical GC-MS methods that contribute to an improved identification and quantification of various PFAS (both currently regulated and emerging PFAS) in selected food and food packaging matrices. Of particular interest as a food contact material are native and recycled polymers such as PET. Besides, various techniques, including solvent-free variants such as thermal desorption GC-MS, will be tested for a quick and easy analysis. Multiple derivatization approaches, which cover different PFAS subgroups, will also be tested and evaluated. This poster will present the overall project objectives and first results. Acknowledgment: The project (23IND13, ScreenFood) has received funding from the European Partnership on Metrology, co-financed from the European Union’s Horizon Europe Research and Innovation Programme and by the Participating States.zeige mehrzeige weniger
