为研究和调查广州市场在售中低端酒中的氨基甲酸乙酯含量，采用固相萃取方式对酒样进行前处理， D5-氨基甲酸乙酯为内标，使用气相色谱串联质谱（GC-MS）定量测定含量。结果表明，在20～200μg/L浓度范围内线性相关系数为0.9996，检出限为0.0018 mg/kg，回收率在75.90%～103.23%之间，精密度在1.43%～3.95%。具有良好的重现性。所有样品中，啤酒和米酒未检出，其他各种酒精饮料中都含有一定量的氨基甲酸乙酯，平均含量大小依次为白兰地＞梅酒＞黄酒＞白酒＞药酒＞果酒＞葡萄酒。

In order to measure the content of ethyl carbamate (EC) in low-end alcoholic beverage in Guangzhou market, gas chromatography-mass spectrometry (GC-MS) with internal standard method was adopted in the experiments (solid phase extraction used for wine samples pre-treatment and D5-ethyl carbamate used as the internal standard). The results suggested that, the linear correlation coefficient was 0.9996 within EC concentration range of 20μg/L to 200μg/L, the detection limit was 0.0018 mg/kg, the recoveries and RSD were 75.90%~103.23%and 1.43%~3.95%respectively. Among all the alcoholic samples, no EC detected in beer and in rice wine, other alcoholic beverages contained EC more or less (the average EC content in brandy>in plum wine>in yellow rice wine>in liquor>in medicinal wine>in fruit wine>in grape wine).
