ISO 11338-2:2003 (R2020)

ISO 11338-2:2003 specifies procedures for sample preparation, clean-up and analysis for the determination of gas and particle phase polycyclic aromatic hydrocarbons (PAH) in stack and waste gases. The analytical methods are capable of detecting sub-microgram concentrations of PAH per cubic metre of sample, depending on the type of PAH and the flue gas volume sampled. The methods described in ISO 11338-2:2003 are based on either high performance liquid chromatography (HPLC) or gas chromatography-mass spectrometry (GC-MS). NOTE ISO 11338-1 describes three methods and specifies minimum requirements for the sampling of PAH in stack and waste gases.
