摘要

本文对气相色谱法测定醇类产品中挥发性化合物的问题进行了广泛的研究。采用传统内标法、先进内标法和外标法三种分析方法对一排重量法配制的标准溶液进行了分析。将“乙醇内标法”的主要分析特性和计量参数与传统方法进行了比较。结果表明,该方法可以得到正确的挥发物浓度值,相应的计量特性通常较好。

The establishment of metrological characteristics of the method “Ethanol as Internal Standard” for the direct determination of volatile compounds in alcoholic products
An extensive study concerning the problem of volatile compounds determination in alcoholic products by gas chromatography has been undertaken in the paper. A row of gravimetrically prepared standard solutions was analysed with three analytical methods: traditional method of internal standard, advanced method of internal standard and external standard method. The main analytical characteristics and metrological parameters of the “Ethanol as Internal Standard” method were compared with the traditional approaches. It was shown that this method leads to correct values of volatiles concentrations and the corresponding metrological characteristics are generally better.
