Second Announcement - Interlaboratory Study (ILS) on the Determination of Brominated Contaminants, PCNs and CPs in Fish Oil 2022/23
10 months ago
This interlaboratory study (ILS) on the determination of several brominated contaminants (BCons), polychlorinated naphthalenes (PCNs) and chlorinated paraffins (CPs) in fish oil is organized by the EURL for halogenated POPs in Feed and Food to be performed between May and September 2022 (first deadline, closed), April 2023 (second deadline) and until October 2023 (third round). The objective is to characterize a quality control material for method development purpose and quality control during routine analysis. Therefore up to five sets of results for all analyte groups can be reported until each deadline using the same or different methods. In addition, the focus is on the assessment of intra- and interlaboratory comparability of results from PBDEs, HBCDDs, TBBPA, eBFRs, PBDD/Fs, PXDD/Fs, PCNs and CPs in two fish oil samples.
As a second exercise ready to measure solutions of CP technical mixtures are prepared to assess intra- and interlaboratory comparability of CP results. Laboratories performing CP analysis, or even just starting to analyse CPs, are encouraged to submit at least total CP results for fish oil and technical mixture samples.
Official laboratories, research laboratories, universities and commercial laboratories performing the analysis of samples taken by food business operators are invited to participate in this interlaboratory study.
