摘要: 在国产SC-6气相色谱仪上使用FID和GDX-102填充柱,甲醇作内标,用峰高比测定酒精饮料中的乙醇含量。对无水乙醇、两种米酒、1种葡萄酒和1种啤酒分别进行了10次平等测定,其CV依次是0.010、0.021、0.0059和00082。可定量回收添加的乙醇。方法具有简便快速的特点。

Abstract: In this parper FID and GDX- 102 packed column was used. Methanol was used for inner standrdination and quantitation of ethanol depending on chromatographic peak high ratio.We made 10 determinnation for anhydrous alcohol. two kinds of spirits distilled from riece .one wine and one beer.CVs of these samples are respectively 0.010 0.02 1 .0.0059.0.0082 and 0.0067.The added alcohol canbe recovered in definite quantitg.The method is easy and fast to operate.
