In this study, we evaluated the quantitative capabilities of a GC-APCI trapped ion mobility (TIMS) TOF platform for the determination of ultra-trace levels of polychlorinated dibenzo-p-dioxins (PCDD/Fs) and polychlorinated biphenyls (PCBs) in complex food matrices. Using a Bruker timsTOF Pro 2 instrument, three fat-based proficiency test samples - fish oil, palm oil, and milk fat - were analyzed and compared to a validated GC-sectorHRMS method, in accordance with the criteria set by Commission Regulation (EU) 2017/644. Linearity was confirmed across broad dynamic ranges, with relative response factor (RRF) precision consistently below 20 %.
