建立一种适用于蒸馏酒中氨基甲酸乙酯的检测方法。采用减压蒸馏法除去样品中的乙醇；以乙腈-0.1%甲酸为流动相，经 C18柱高效液相色谱分离，选择电喷雾正离子模式，以质子化氨基甲酸乙酯分子离子[M+H]+90.055为定量离子进行检测。结果表明，在10～500μg/L 浓度范围内氨基甲酸乙酯呈线性，其相关系数＞0.999，方法精密度为6.4%，加标回收率为86%～117%。本方法操作简单，检测时间短，灵敏度高，结果精确。

A method for detecting ethyl carbamate in distilled liquor had been developed. Firstly, alcohol in liquor samples was removed by vacu-um distillation, then acetonitrile and 0.1 % formic acid used as mobile phase, and liquor samples were separated by C18 column HPLC, electro-spray positive ion mode was selected, and [M+H]+ 90.055 was used as the quantitative ion for the detection. The experimental results showed that, ethyl carbamate was linear within the concentration range of 10~ 500 μg/L, its correlation coefficient was above 0.999, the precision was 6.4 %, and the recovery rate was between 86 % and 117 %. HPLC-MS for the detection of ethyl carbamate in distilled liquor had the advantages includ-ing simple operation, short detection time, high sensitivity, and precise detecting results etc.
