摘要:

建立了气相色谱三重四极杆质谱法同时测定化妆品中24种致敏原的分析方法。样品经甲醇超声提取,以多重反应监测模式(MRM)进行定性及定量分析。结果表明,24种致敏原在质量浓度0.1~10.0 mg/L范围内线性关系良好,相关系数r 2>0.993,阴性样品在三个质量浓度水平的加标平均回收率为81.8%~106.7%,相对标准偏差为1.3%~8.7%,方法的检出限为1~3 mg/kg,定量限为10 mg/kg。

Abstract:

A simultaneous determination method was developed for the reliable screening, quantification and confirmation of 24 allergens in cosmetics by gas chromatography triple quadrupole mass spectrometry (GC-MS/MS) . The samples were ultrasonic extracted from cosmetics with methanol, and then qualitative and quantitative analysis was performed by GC-MS/MS under multi reaction monitor mode (MRM) . The results show that the 24 allergens have a good linear relationship in the range of 0.1-10.0 mg/L with correlative coefficients (r 2) larger than 0.993, and the average recoveries range from 81.8% to 106.7% at three spiked levels with relative standard deviations of 1.3%-8.7%. The detection limit is 1-3 mg/kg and the quantification limit is 10 mg/kg.

Key words: gas chromatography triple quadrupole mass spectrometry, cosmetics, allergen
