Detection method of residual polybrominated diphenyl ether in cosmetics with gas chromatography-mass spectrum method

Номер: CN0101718752A
Принадлежит:

The invention relates to a detection method of residual polybrominated diphenyl ether, in particular to a detection method of residual polybrominated diphenyl ether in cosmetics with gas chromatography-mass spectrum method; in the method, a sample is extracted in an accelerating way by solvent, normal hexane is used as extractant, and then gel extraction and Florisil cartridge purification are carried out, and then the gas chromatography-mass spectrum method, selected ion canning detection and an external standard method are used for quantifying. The detection method has the following characteristics that: 1. in the method, the gel extraction and Florisil cartridge purification are firstly combined to measure residual polybrominated diphenyl ether in cosmetics. 2. the solvent is adopted to carry out extraction in an accelerating way, and the gel extraction and Florisil cartridge purification are adopted, the gas chromatography-mass spectrum method is used for quantifying and determining ...
