摘要:

建立了一种分散固相萃取结合气相色谱-三重四极杆串联质谱(GC-MS/MS)测定化妆品中18种有机磷酸酯的方法。样品经乙腈提取,HMR-Lipid填料净化,待测液用HP-5MS UI色谱柱(30.0 m×0.25 mm,0.25 μm)分离,动态多反应监测(dMRM)模式扫描,内标法定量。实验结果表明,18种有机磷酸酯线性关系良好,相关系数(R2)均大于0.99;检出限为0.001~0.050 mg/kg,定量限为0.003~0.100 mg/kg;在低、中、高三种水平添加浓度下,各物质的平均回收率为85.8%~110.6%,相对标准偏差小于9.9%。所建立的方法前处理简单、快速高效、准确性好,可用于化妆品中18种有机磷酸酯的定性定量检测。

Abstract:

A method was established for the determination of 18 organophosphate esters in cosmetics by dispersive solid-phase extraction coupled with gas chromatography-tandem mass spectrometry (GC-MS/MS). The samples were extracted with acetonitrile and purified with an HMR-Lipid sorbent, separated on an HP-5MS UI chromatographic column (30.0 m× 0.25 mm, 0.25 μm), monitored in dynamic multiple reaction monitoring (dMRM) mode, and quantified by the internal standard method. The results show good linearity for all 18 organophosphate esters, with correlation coefficients (R2) greater than 0.99. The limits of detection range from 0.001 to 0.050 mg/kg, and the limits of quantitation are 0.003-0.100 mg/kg. The average recoveries at low, medium and high spiking levels are between 85.8% and 110.6%, with relative standard deviations less than 9.9%. The method features simple sample preparation, rapid and efficient analysis, and accurate quantification, making it suitable for the qualitative and quantitative determination of 18 organophosphate esters in cosmetics.
