GC-7900Baijiu analysis chromatograph

Baijiu is a traditional beverage wine in China, with excellent technology and flavor, and its flavor composition is extremely complex. In order to accurately determine the main flavor components in Baijiu, gas chromatography has become a detection method in Baijiu industry.
GC-7900A type of gas chromatograph equipped with a high-sensitivity hydrogen flame detector and packed column/Capillary column injection system,Combined with the stainless steel packed column and capillary chromatography column specified by the national standard, it can be used for routine detection and trace aroma component analysis.DNPDirect injection of mixed column can be measured in one go14Main alcohols, aldehydes, and estersAcid and other componentscontent,This method has been widely used in Baijiu factories,It has also been listed as the national standard for the detection of luzhou flavor and light flavor liquors. Direct single injection of capillary chromatographic column can accurately quantify more than 50 components, including free organic acids and higher fatty acids, so that people have a new understanding of the content of flavor components in Baijiu and the relationship between the content of flavor components and the quality of flavor. This undoubtedly pushed the quality control and analysis of Baijiu to a new height, and provided a good data guarantee for the microcomputer blending of Baijiu.
Baijiu capillary chromatographic column conforms to GB 10345-2007The analysis requirements for edible alcohol include the ability to detect trace components such as methanol and fusel oil in high-quality edible alcohol.Conduct inspections in accordance with food safety standards such as the National Food Safety Standard for Distilled Liquor and its Blended Liquor (GB 2757-2012) to ensure the safety of methanol12Waiting for safety indicators.
