摘要
建立了多维气相，气质联用（MDGC／GCMS）法测定葡萄酒中氨基甲酸乙酯的检测方法。采用硅藻土固相萃取柱对葡萄酒中氨基甲酸乙酯（EC）进行提取净化，利用MDGC／GCMS对葡萄酒中EC进行检测。结果表明，葡萄酒中Ec与干扰物均得到很好分离，EC在0～1000μg/L范围内线性关系良好（R=0．9993），检出限（S／N=3）为1．0μg／L，加标回收率为82．97％-86．82％，相对标准偏差（RSD）为2．29％；方法的精密度和重复性试验RSD分别为2．42％和2．88％。表明该方法准确度高、重复性和精密度良好，适用于葡萄酒中的氨基甲酸乙酯的检测。
The determination method of ethyl carbamate （EC） in wine was established by multidimensional gas chromatography with gas chromatography mass spectrometric （MDGC/GCMS）. The EC in wine was extracted and purified by diatomaceous earth solid phase extraction column, then was detected by MDGC/GCMS. The results showed that the EC and interfering substance in wine were well separated. EC had a good linear relationship in the rage of 0-1 000 μg/L （R=0.999 3）, the limit of detection （S/N=3） was 1.0 μg/L, the adding standard recover rate was 82.97%-86.82%, relative standard deviation （RSD） was 2.29%. The RSD of the precision and repeatability tests of the method were 2.42% and 2.88%, respectively, which indicated that the method had high accuracy, good repeatability and precision, and it was suitable for the detection of EC in wine.
