摘 要:建立了化妆品中双酚A残留的高效液相色谱-串联四极杆质谱联用测定方法。样品经碱性乙腈提取,氨基固相小柱净化而后测定。方法在2.0~100.0μg/L范围内呈良好线性,相关系数为0.99998,方法的检出限为0.02 mg/kg。在0.10,1.0,10.0 mg/kg 3个加标水平下,加标回收率为92.4%~98.8%,相对标准偏差为6.0%~9.4%。A LC-MS-MS method was developed for the determination of bisphenol A residues in cosmetics.The sample was extracted by alkaline acetonitrile in ultrasonic,then cleaned up by NH2 solid-phase extraction cartridge and analyzed by LC-MS-MS.Under the optimal conditions,good linear relationship was obtained in the range of 2.0~100.0 μg/L for bisphenol A with correlation coefficient of 0.99998.The limit of detection was 0.02 mg/kg.The recoveries at three spiked levels of 0.10,1.0,10 mg/kg were between 92.4% and 98.8%,and RSDs were between 6.0%and 9.4%.
