HJ 734-2014 Stationary source emission -Determination of volatile organic compounds-Sorbent adsorption and thermal desorption gas chromatography mass spectrometry method
Stationary source emission -Determination of volatile organic compounds-Sorbent adsorption and thermal desorption gas chromatography mass spectrometry method
This standard specifies the sorbent adsorption and thermal desorption / gas chromatography mass spectrometry method for determination of 24 volatile organic compounds in stationary source emission.
This standard is applicable to determination of 24 volatile organic compounds in stationary source emission; the 24 volatile organic compounds include: acetone, isopropanol, hexane, ethyl acetate, benzene, hexamethyldisiloxane, 3-pentanone, heptane, toluene, cyclopentanone, ethyl lactate, butyl acetate, PGEA, ethyl benzene, p-xylene/m-xylene, 2-heptanone, styrene, o-xylene, anisole, benzaldehyde, 1-decene, 2-nonanone and 1- dodecene. Methods specified in this standard are also applicable to other volatile organic compounds which are verified.
Where the sampling volume is 300 ml, the method detection limit of this standard is 0.001~0.01 mg/m3 and the lower limit for determination is 0.004~0.04 mg/m3, as detailed in Appendix A.
