摘  要:介绍了用气相色谱法测定白酒中已酸乙酯的两种定量方法:内标法和外标法,并分别对三个白酒样品进行测定。测定结果的RSD值依次为0.43%~0.86%和0.46%-1.40%,说明两种定量方法在检测白酒中已酸乙酯时结果无显著性差异,可将外标法推广到日常的白酒检测工作中。This paper introduces the determinating methods of Hexanoic Acetate in Chinese spirits by two quantitative analysis: Internal Standard Method and External Standard Method with Gas Chromatography, by which three samples are determinatod. The values of RSD at the range of 0.43% - 0.86% are obtained for Internal Standard Method and of 0.46% - 1.40% for External Standard Method. It illuminates that there is no remarkable difference in the experiment between two quantitative analysis methods by determinating Hexanoic Acetate in Chinese alcohol, and the External Standard Method can be widely used in determinating the Chinese alcohol.
