| Abstract: | "A method using a domestic gas chromatograph controlled by computer with a homemade DNP packed column for the determination of major flavor components in Chinese spirtis is described. This chromatograph was developed under the sponsorship of the Ministry of Science and Technology. Optimizations of the operating parameters were undertaken in order to establish the chromatographic conditions suitable for isothermal and programmed temperature gas chromatography. The expanded analytical objects, including acetone, iso-valeraldehyde, 2-pentanone, 2-pentanol, acetoin, could also be quantitatively determined along with more than ten major components such as alcohols, esters, aldehydes, therefore, a total of 18 flavor components were accurately determined by this method. Under the selected chromatographic conditions, the instrument showed good stability and the repeatability of quantitative results was satisfactory. The suitability of this gas chromatograph is also discussed" |
