毛细管柱气相色谱法同时测定白酒中的乙酸乙酯、甲醇、异丁醇、异戊醇和己酸乙酯

Gas Chromatography Method for Simultaneous Determination of Ethyl acetate, Methanol, Isopropyl Alcohol, Isoamyl alcohol and Ethyl hexanoate in Distilled Spirit

本文建立了毛细管柱气相色谱法同时测定白酒中的乙酸乙酯、甲醇、异丁醇、异戊醇和己酸乙酯，使用FID检测器进行检测，采用内标法进行定量分析。结果显示：乙酸乙酯、已酸乙酯、甲醇、异丁醇和异戊醇，平均回收率均在87．9—98．7％之间，6次测定的相对标准偏差均小于2．04％，该方法具有准确、简单及灵敏度高的特点，能够适应大规模样品的快速分析要求。

This paper reported the methods for determination of Determination of ethyl acetate, methanol, isopropyl alcohol, isoamyl alco- hol and Ethyl hexanoate, in distilled spirit by gas Chromatography. The determinations were utilized FID detector and the contents were deter- mined by internal standard method for quantitative analysis. The results showed that tThe recovery rates were 87.9-98.7 , and 6 parallel determi- nation of the relative standard deviation is less than 2.04%. This method is rapid, simple and accurate, high sensitivity for measurements of ben- zene homologues. Its can adapt to quick analysis the large samples.
