Determination of ethanol in ethanol / water system by filling column gas chromatography
摘要
Abstract
A packed column gas chromatography method was established for the determination of ethanol in ethanol / water system and the best conditions was obtained by investigating the factors influenced the measure of ethanol in ethanol / water system, such as chromalographic column, gasification chamber temperature, detector temperature , column temperature and carrier gas. The optimum detection conditions: gasification chamber temperature is 160 ℃, detector temperature is 160 ℃, column temperature is 140℃, when carrier gas reached 50 mL/min, the chromatographic detection could reach best. The ethanol in ethanol / water system was quantified by the relative correction factor and peak area normalization method. The relatively standard deviati of method was 0.052 4-0.033 2.关键词
