Determination of Hexabromocyclododecane Diastereoisomers in Electrical and Electronic Products Using Accelerated solvent Extraction/LC-MS/MS
摘要
Abstract
A method was established for the determination of hexabromocyclododecane in electrical and electronic products by accelerated solvent extraction technique combining with liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. The sample was crushed and then extracted with toluene as the extracting agent by accelerated solvent extraction. The extract was concentrated and then detected by LC-MS/MS.Electro-spray ionization source was applied. The confirmation ion pairs were 640.5/78.9 and 640.5/80.9, and the quantification ion pairs were 640.5/78.9. The limit of determination was 0.05 mg/ kg(P-HBCD), 0.01 mg/ kg (a-HBCD, y-HBCD). The recoveries were between 88.8% and 104.0% in the spiked range of 0.1-10 mg/kg, and the relative standard deviations (RSDs) were between 3.0% and 6.5%. The experiment results indicate that the method is rapid, sensitive, accurate and can meet the correlative requirements for determination.关键词
