Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a microcomputer-controlled domestic gas chromatograph and a self-made DNP packed column to determine the main aroma components in liquor. Through the optimization of various operating parameters, the isothermal and programmed temperature rise time were established. Appropriate chromatographic conditions. In addition to the determination of more than ten main alcohol, ester, and aldehyde components, this method also expands the analysis objects to acetone, isovaleraldehyde, 2-pentanone, 2-pentanol, and 3-hydroxy-2 -Butanone and other components, so that the components that can be accurately determined by this technology are increased to 18. Under the selected chromatographic conditions, the instrument has good stability, and the reproducibility of the quantitative results of each fragrance component is good.
