【Abstract】 In this paper, a combined technique of gas chromatography With ECD and HA for the determination of diacetyl in the saccharomyces cerevisiae metabolite has been studied. A simple, fast and accurate analytical method was dereloped. Some factors which affect the sensitivity and accuracy of the analytical metyod were investigated and operating codition were optimized.更多还原
