Abstract

Two test materials were dispatched begin of July 2006. Each participant received two liquid smoke condensate test materials to be analysed for the 15+1 EU priority polycyclic aromatic hydrocarbons (PAHs). In total 28 sets of samples were sent to participating laboratories in 13 countries. Both test materials contained the 15+1 EU priority PAHs. The assigned value (X) for each analyte was calculated from the participant's results applying robust statistics. The target standard deviation (sp) was calculated using the modified Horwitz equation as proposed by Thomson. The resulting sp was then used in conjunction with the assigned value to derive z-scores from the participant's results.
