摘要
[目的]建立固相支持液液萃取气相色谱-质谱联用测定电子烟液中的16种多环芳烃的方法.[方法]电子烟烟液样品中加入少量水,振荡均匀,充分分散在硅藻土固相支持液-液萃取柱中,用环己烷萃取,萃取液浓缩后,采用气相色谱-质谱联用仪实现电子烟烟液中16种多环芳烃的测定.[结果]试验表明,16种多环芳烃在0.02～1.00 mg/L范围内线性关系良好(R2＞0.999),加标回收率在91％-101％,日内精密度(RSD)在2.74％ ～ 6.54％,日间精密度(RSD)在3.04％ ～7.56％,检出限(LOD)为0.012 ～0.133 ng/g.[结论]与传统方法相比,该方法检测时间显著缩短,有机溶剂消耗较少,更符合绿色分析的要求,并可降低分析成本.
Abstract
[Objective] The aim was to use supported liquid extraction gas chromatography-mass spectrometry for determination of 16 PAHs in e-cigarette liquid.[Method] Adding a small amount of water into e-cigarette liquid samples,homogeneous oscillatory fully decentralized in diatomite solid phase supported liquid-liquid extraction column,extraction with cyclohexane and after concentration by GC-MS realizes the ecigarette liquid of 16 kinds of PAHs determination.[Result] 16 PAiHs had good linear relationshp (R2 ＞ 0.999) within the range of 0.02-1.00 mg/L,the standard recovery rate was 91％-101％,intra day precision(RSD) was 2.74％-6.54％,precision day to day(RSD) was 3.04％-7.56％.The detection limit ranged from 0.012 to 0.133 ng/g.[Conclusion] Compared with traditional method,this method can significantly shorten detection time,reduce consumption of organic solvent,decrease analysis cost,which meets the requirements of green analysis.
