建立了顶空液相微萃取/气相色谱仪-质谱联用测定葡萄酒中的氨基甲酸乙酯的方法。对影响萃取效率的实验条件进行了优化。采用Rtx-Wax毛细管柱进行检测，以癸烷为萃取溶剂，在60℃、搅拌速度为200r/min条件下对1mL葡萄酒样品萃取30min。该方法对氨基甲酸乙酯的富集倍数为62；在100～1600μg/L的范围内线性关系良好。相关系数为0.9999；氨基甲酸乙酯的检出限为1μg/L（S/N=3）。实际酒样的加标回收率为81.0%～103.1%。

Headspace liquid-phase micro-extraction (HS-LPEM) coupled with gas chromatography-mass spectrometry (GC-MS) was used to determine the ethyl carbamate of wines. Some main experimental parameters that affect the extraction efficiency were optimized. Decane was selected as extraction solvent. The extraction was carried out at 60℃in a 2mL vial filled with 1mL of sample solution at a stirring rate of 500r/min for 30min. The enrichment factors for the ethyl carbamate was 62. The linear range for the quantification of the ethyl carbamate was 100~1600 μg/L(R2=0.9999) . The limit of detection was 1μg/L(S/N=3)for the ethyl carbamate. Recovery was 81.0%~103.1%.
