摘　　要：用气相色谱内标法对黄酒和调味料酒中酒精度含量进行测定的方法,试验采用FID检测器,内标法,自动进样,在建立的气相色谱条件下进行了方法验证,结果表明:酒精度检出限为0.004%vol,(进样量为0.5μL,S/N=3),标准曲线的线性范围分别为:0.01%~0.1%vol(R2=0.99976),样品加标回收率分为:94.7%~99.5%,相对标准偏差RSD(n=10)酒精度1.86%。该方法回收率高、重现性好,是一种准确稳定操作快速简单的检测方法。A method for quick determination of alcohol content in yellow rice wine and flavoring wine by GC internal standard method was established.The method was performed by GC with FID detector,internal standard method and automatic sampling.The results showed that the detection limit of alcohol was 0.004%vol(injection 0.5 uL,S/N=3),and the linear range of the standard curve was 0.01%~0.1%vol(R2=0.99976).The recoveries were 94.7%~99.5%,the relative standard deviation(RSD)(n=10)was 1.86%.The method has high recovery rate and good reproducibility.The method is fast and simple,accurate and stable.
