Stationary source emissions. Determination of gas and particle-phase polycyclic aromatic hydrocarbons - Sample preparation, clean-up and determination1 Scope This part of ISO 11338 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 this part of ISO 11338 are based on either
