A gas-liquid chromatographic (GLC)-mass spectral (MS) method for the determination and confirmation of urethane in wines has been developed. Analyses of domestic and imported wines indicated urethane to be present at levels ranging from 1 to 20 microng/L. Recoveries of urethane from wines fortified at 10 ppb (microng/L) ranged from 50 to 100% with an average value of 71%. GLC-MS was used to confirm the identity of urethane in wine extracts in which GLC indicated the presence of urethane.
已开发出一种用于测定和确证葡萄酒中氨基甲酸乙酯的气液色谱（GLC）-质谱（MS）方法。对国产和进口葡萄酒的分析表明，氨基甲酸乙酯的含量范围为1至20微克/升。在添加了10 ppb（微克/升）氨基甲酸乙酯的葡萄酒中，其回收率为50%至100%，平均值为71%。当GLC表明葡萄酒提取物中存在氨基甲酸乙酯时，使用GLC-MS来确证其身份。
