This standard 25/30480159 DC BS EN 18261 Compost and digestate - Determination of polycyclic aromatic hydrocarbons (PAH) by gas chromatography (GC) and high performance liquid chromatography (HPLC) is classified in these ICS categories:

• 65.080 Fertilizers

This document specifies different methods for quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) (see Table 1) in compost or digestate, using GC-MS, GCMS/MS or HPLC UV DAD/FLD covering a wide range of PAH contamination levels (see Table 1). When using fluorescence detection, acenaphthylene cannot be measured. Table 1 — Target analytes of this document [...table not reproduced...] The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract. This document contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used. The method may be applied to the analysis of other PAH not specified in the scope, provided suitability is proven by proper in-house validation experiments.
