Scope

This standard specifies a high-resolution gas chromatography-high-resolution mass spectrometry method for the determination of polybrominated diphenyl ethers in ambient air. This standard applies to BDE 7, BDE 15, BDE 17, BDE 28, BDE 47, BDE 49, BDE 66, BDE 71, BDE 77, BDE 85, BDE 99, BDE 100, BDE 119, Determination of a total of 26 polybrominated diphenyl ethers: BDE 126, BDE 138, BDE 153, BDE 154, BDE 156, BDE 175/183, BDE 184, BDE 191, BDE 196, BDE 197, BDE 206, BDE 207 and BDE 209. . See Appendix A for details. When the sampling volume is 1000 m3 (standard state) and the concentration volume is 20 l, the method detection limit of di- to nona-BDE is 0.02 pg/m3 ~ 0.4 pg/m3, and the lower limit of determination is 0.08 pg/ m3～1.6 pg/m3; the detection limit of decabromodiphenyl ether is 1 pg/m3, and the lower limit of determination is 4 pg/m3. When the sampling volume is 300 m3 (standard state) and the concentration volume is 20 l, the method detection limit of di- to nona-BDE is 0.05 pg/m3 ~ 2 pg/m3, and the lower determination limit is 0.20 pg
