3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Polychlorinated biphenyls; PCBs
a polychlorinated compound formed by the substitution of hydrogen on a biphenyl benzene ring, and a type of persistent organic pollution that has a toxic effect on the living organism.
The general name of the dye.
4 Principle
Using hexane as extraction solvent, ultrasonically extracting polychlorinated biphenyls from samples, using gas chromatograph equipped with electron capture detector
(GC/ECD) or gas chromatography-mass spectrometry (GC/MS) for detection.
Note. Other approved suitable solvents may also be selected as the extraction solvent.
5 reagents and materials
Unless otherwise specified, only reagents identified as chromatographically pure and of the above purity were used in the analysis.
5.1 Hexane. purity ≥ 98% (mass fraction) or known purity.
5.2 Polychlorinated biphenyl mixed standard solution. PCB28, PCB52, PCB101, PCB118, PCB138, PCB153 and PCB180 (see
Table A.1) and the like, each substance has a concentration of 10 mg/L.
5.3 PCB209 quantitative internal standard solution. 100mg/L.
