Water quality. Determination of polycyclic aromatic hydrocarbons (PAH) - Determination of six PAH by high performance thin layer chromatography with fluorescence detection after liquid-liquid extraction Ingestion-build-50790 see ISO 106841 Scope This part of ISO 7981 specifies the determination of six selected PAH in drinking water by high performance thin layer chromatography with fluorescence detection after liquid liquid extraction. The six PAH are: fluoranthene, benzo[b]fluoranthene, benzo[a]pyrene, benzo[k]fluoranthene, indeno[1,2,3 cd]pyrene, and benzo[ghi]perylene (see Table 1). A screening method (method A) is described to exclude those samples containing less than 20 % of the
