HJ 734-2014 Waste gas from stationary pollution sources-Determination of volatile organic compounds-Solid phase adsorption-thermal desorption-Gas chromatography-mass spectrometry
Warning: Volatile organic compounds are flammable substances, some of which are toxic substances, and attention should be paid to safety when preparing standard samples and storing them. When sampling in potentially explosive environments, special attention should be paid to the safety of sampling equipment and operations.

1 Scope of application

This standard specifies the solid-phase adsorption-thermal desorption/gas chromatography-mass spectrometry method for the determination of 24 volatile organic compounds in waste gas from stationary pollution sources.

This standard is applicable to the determination of 24 kinds of volatile organic compounds in waste gas from stationary pollution sources. The 24 kinds of volatile organic compounds include: acetone, isopropanol, n-hexane, ethyl acetate, benzene, hexamethyldisiloxane, 3-pentanone , n-heptane, toluene, cyclopentanone, ethyl lactate, butyl acetate, propylene glycol monomethyl ether acetate, ethylbenzene, p/m-xylene, 2-heptanone, styrene, o-xylene, benzyl Ether, benzaldehyde, 1-decene, 2-nonanone, 1-dodecene. Other volatile organic compounds can also use this method after verification.

When the sampling volume is 300 ml, the detection limit of the method of this standard is 0.001~0.01 mg/m3, and the lower limit of determination is 0.004~0.04 mg/m3. See Appendix A for details.
