HJ 868-2017 (English Version) PDF

Scope: This standard specifies a high-performance liquid chromatography method for the determination of phthalate ester compounds in ambient air. This standard applies to dimethyl phthalate, diethyl phthalate, diisobutyl phthalate, dibutyl phthalate, and benzyl butyl phthalate in the gas phase and particulate matter in ambient air. Determination of 7 kinds of phthalate esters including di(2-ethylhexyl) phthalate and di-n-octyl phthalate. If verified, this standard is also applicable to the determination of other phthalate ester compounds. When the sampling volume is 144m3 (under standard conditions) and the concentration volume is 1.0 ml, the detection limit of the method is 0.002μg/m3 ~ 0.006 μg/m3, and the lower limit of determination is 0.008μg/m3 ~ 0.024μg/m3. See Appendix A for details.
