摘要
本文采用内标法,以乙酸正丁酯为内标物,用气象色谱法在恒温条件下,采用毛细管色谱柱和氢火焰检测器,测定了不同批号汾酒中芳香成分乙酸乙酯的含量,并进行了对比。实验测得的乙酸乙酯回收率在81.6%~115.2%之间,变异系数<5%。证明该法可用于酒中芳香成分乙酸乙酯的测定。该法快速、简便,重复性好,适用于常规质量检测。
Based on GC-Method and internal calibration principle, under the condition ofconstent tempreture,the ethyl acetate in different distilled spirits was determined by usingcapillary column and hydrogen flame ionization deterctor. The guantitative conective fac-tor of the ethyl-acetate was determined. The average rate of recovery of ethyl-acetateamount was81.6%~115.2%and the coeffient of rariation was less than 5%The methodwas suitable to the determination of cthyl acetate in disilled. spirit. In addion,the methodis simple , rapid, reproductive and available to routine guality control.
