AMBIENT AIR - DETERMINATION OF PARTICLE-PHASE POLYCYCLIC AROMATIC HYDROCARBONS BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY (ISO 16362:2005, IDT)
This Malaysian 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 m3/h (“medium/high-volume sampler”). In any case, the linear face velocity at the collection filter should range between about 0,5 m/s and 0,9 m/s.
The method has been validated for sampling periods up to 24 h. The detection limits for single PAHs and the standard deviations resulting from duplicate measurements are listed in 9.2 and Annex D respectively.
This Malaysian Standard describes a sampling and analysis procedure for PAH that involves collection from air onto a filter followed by analysis using high performance liquid chromatography u
