Report on the Inter-Laboratory Comparison Test on 15+1 EU Priority PAHs in Acetonitrile

Abstract

The Institute for Reference Materials and Measurements (IRMM) of the European Commission's Joint Research Centre hosts the Community Reference Laboratory for Polycyclic Aromatic Hydrocarbons in Food (CRL-PAH). One of its core tasks is to organise inter-laboratory comparisons (ILCs) for the National Reference Laboratories (NRLs). This report presents the results of the 1st ILC of the CRL-PAH on the determination of the 15+1 EU priority PAHs in acetonitrile, which was conducted along the lines of the International Harmonized Protocol for the Proficiency Testing of Analytical Chemical Laboratories. The test material used in this exercise was a solution of the 15+1 EU priority PAHs in acetonitrile. The solution was prepared gravimetricallyJRC.D.8-Food safety and qualit
