Description:This standard stimulates the determination of benzene in the air content of solid adsorption/hot stripping - gas chromatography.
this standard applies to the ambient air and benzene, toluene, ethyl benzene in indoor air, o-xylene, m-xylene, p-xylene, the determination of isopropyl benzene and styrene. This standard applies to interesting and low concentration on the determination of benzene content in exhaust gas.
