摘　　要：目的 建立一种白酒中环氧氯丙烷的完善、准确检测方法 ,幵作为白酒添加人工合成甘油的辅助判定手段。方法 白酒中的环氧氯丙烷经过二氯甲烷萃取、浓缩和高弹石英毛细管柱分离,利用气相色谱-质谱联用仪(gas chromatography-mass spectrometer,GC-MS)迚行测定,幵以灵敏度最高的离子对迚行定量分析。结果 该方法相对标准偏差(relative standard deviation, RSD)<10%,加标回收率为75.5%～89.0%,最低检出限为1.0μg/L。结论 该方法灵敏度高,准确性好,适用于白酒中环氧氯丙烷的测定。Objective To establish a perfect and accurate detection method for epichlorohydrin in liquor, and as an auxiliary determination method for the addition of synthetic glycerol in liquor. Methods Epichlorohydrin in liquor was extracted and condensed by dichloromethane, separated by high elastic quartz capillary column, and determined by gas chromatography-mass spectrometer(GC-MS). The ion pair with the highest sensitivity was used for the quantitative analysis. Results The relative standard deviations(RSDs) of method were less than 10%, the recovery rates were 75.5%-89.0%, and the limit of detection was 1.0 μg/L. Conclusion This method is sensitive and accurate, which is suitable for the determination of epichlorohydrin in liquor.
