Ambient air. Determination of particle-phase polycyclic aromatic hydrocarbons by high performance liquid chromatography Ingestion-build-201039 there is a need to1 Scope This International Standard specifies sampling, clean up and analysis procedures for the quantitative determination of low volatility (particle bound) polycyclic aromatic hydrocarbons (PAHs) in ambient air. For sampling, a low volume or a medium high volume sampling device may be used. Sampling times between 1 h and 24 h are possible. The sampling volume flowrates can range from 1 m3 h to 4 m3 h (low volume sampler) or from 10 m3 h to about 90
