Scope

This Standard specifies using the activated charcoal adsorption/carbon disulfide
desorption-gas chromatography method for the determination of benzene and its
analogies in the air.
This Standard is applicable to the determination of benzene, toluene, ethylbenzene, o-
xylene, m-xylene, p-xylene, cumene and styrene in ambient air and indoor air. This
standard is also applicable to the determination of benzene and its analogies in low-
humidity exhaust gas at room temperature.
When the sampling volume is 10L, the method detection limits of benzene, toluene,
ethylbenzene, o-xylene, m-xylene, p-xylene, cumene and styrene are all 1.5×10−3
mg/m3, and the lower limit of determination is 6.0×10−3 mg/m3.

Summary	This standard specifies the determination of BTEX in air activated carbon adsorption/desorption of carbon disulfide gas chromatography. This standard applies to the ambient air and indoor air, benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, cumene and styrene determination. This standard also applies to room temperature, low humidity exhaust BTEX determination.
