Ambient air. Determination of particle-phase polycyclic aromatic hydrocarbons by high performance liquid chromatography Ingestion-build-201039

Ambient air. Determination of particle-phase polycyclic aromatic hydrocarbons by high performance liquid chromatography Ingestion-build-2010391 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

This International Standard specifies a lossless compression algorithm to reduce the number of bytes required to represent data
