Alcohol is one of the main components of rice wine, which is not only different from the characteristics of rice wine, but also has an influence on the quality and quality of rice wine. At present, the detection method of fusel oil is mainly used directly into the gas chromatography, but due to impurities in rice wine is more, especially in the sampling process, samples of sugar Coke will not only pollution liner, lead to the emergence of tailing, ghost peak current chromatogram.
Tengzhou City Xiangying Analysis Technology Co., Ltd. the XiangyingGC7990plus to establish a set of static headspace gas chromatography method for analyzing the volatile alcohol content in yellow rice wine. Methods: in the headspace sampling bottle, the alcohol in the gas-liquid two-phase equilibrium distribution, the headspace gas samples were analyzed, and the results were accurate and reliable.
醇是稻米黄酒的主要成分之一,不仅区别于非稻米黄酒的特征指标,而且影响着黄酒的质量和品质。目前对于杂醇油的检测方法主要是采用直接进样的气相色谱法,但是由于黄酒中杂质较多,尤其在进样过程中,样品中的糖分焦化,不但会污染衬管,导致色谱图出现拖尾、鬼峰等现。
滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus建立一套静态顶空气相色谱法测定黄酒中挥发醇含量的分析方法。方法:在顶空进样瓶中,醇在气液两相平衡分配后,取顶部空间气态样品进行气相色谱分析，结果准确可靠。
