Fixed source of waste gas Determination of phthalate
Determination of cesium esters by fixed source of waste gas Details:

Fixative: (35%-phenyl)-methylpolysiloxane
Model: HH-35
Specification: 30m*0.25mm*0.25um
Application: HJ 869-2017 Waste gas from stationary sources Determination of phthalates Gas chromatography (release)

This standard specifies gas chromatographic methods for the determination of phthalate esters in organized exhaust gases from stationary sources.
This standard is applicable to dimethyl phthalate, diethyl phthalate, dibutyl phthalate, butyl benzyl phthalate and phthalic acid in organized exhaust gas from stationary sources. Determination of a total of 6 decanoates of -ethylhexyl) ester and di-n-octyl phthalate.
This standard also applies to the determination of other phthalates if verified.
When the sampling volume is 1 m3 (dry sampling volume under standard conditions), the detection limit of the method is 0.4 μg/m3 to 0.8 μg/m3, and the lower limit of determination is 1.6 μg/m3 to 3.2 μg/m3. See Appendix A for details.
