Stationary pollution source waste gas determination of benzene series
Stationary pollution source waste gas Determination of benzene series detailed information:

Name: Capillary Column

Specification: 30m*530um

Model: Polyethylene glycol PEG-20M

Application: fixed pollution source waste gas determination of benzene series air bag sampling/direct injection-gas chromatography

Stationary pollution source waste gas Determination of benzene series Air bag sampling/direct injection-gas chromatography (draft for comments)

This standard specifies the air bag sampling/direct injection-gas chromatography method for the determination of benzene series in waste gas from stationary sources.
This standard is applicable to the determination of benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, cumene and styrene in waste gas from stationary sources.
When the injection volume is 1.0ml, the detection limit of benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, cumene and styrene is 0.2~0.6mg/m3, and the lower limit of determination is 0.4 ~2.4mg/m3, see Appendix A for details.
