Description
Technical field
This utility model relates to a kind of mensuration system, particularly relates to the mensuration system of ethyl acetate and ethyl hexanoate in a kind of Chinese liquor。
Background technology
Chinese liquor is in process of production, acid generates various esters with alcohol fermentation, second Ester is the main part of distilled spirit fragrance, various ethyl esters have respective odor characteristic, the more pure gracefulness of fragrance of ethyl acetate, when containing ethyl acetate is more, other esters are less, Chinese liquor then presents the style that delicate fragrance is graceful, and custom is called " phoenix odor type "；If various esters are more in Chinese liquor, particularly ethyl acetate, ethyl lactate, ethyl hexylate, give off a strong fragrance honest, long times of aftertaste, this kind of Chinese liquor is called " Luzhou-flavor "；Distillation type Chinese liquor is different because of preparation process, is substantially free of aromatic ester composition。Owing to how much the difference of various esters and content determine fragrance and the style of Chinese liquor, the determination of fragrant liquor is played a leading role by it。
Fen-flavor type white spirit is simple because of its production technology, and fragrance is strong, cheap, and therefore the wine of its yield and drink other odor type of amount ratio is much higher, it has also become indispensable beverage in daily life。Ethyl acetate is the main aroma of fen-flavor type white spirit, is delicate fragrance when ethyl acetate is rare, is that pears are fragrant time dense。Liquor-making industry develops rapidly, Yield and quality all improves a lot, for strengthening technical management, improvement of production process, improving product quality further, fragrance ingredient distinctive in Chinese liquor has been studied by the sixties once paper using chromatographic technique, but paper chromatography is because of shortcomings such as speed are slow, accuracy is low, so this technology can not obtain penetration and promotion always, the analysis chemical method of Chinese liquor being surveyed fragrance component, the result obtained can only be total ester。
Chromatography is a kind of isolation technics, and gas chromatography (GasChromatography, GC) adopts gas (gas that conventional nitrogen, hydrogen etc. self does not react with tested component) as a kind of chromatography of mobile phase。Fixing phase time is flowed through when mobile phase carries the mixture being intended to separate, different in kind due to component each in mixture, also different with the fixing degree acted on mutually, thus component alternate has different partition coefficients two, after distribution quite repeatedly, it is short that each component has length to have in the holdup time fixed in mutually, so that each component flows out chromatographic column successively and separated。According to the physics or the physicochemical properties that flow out component, select suitable detector, though obtaining the curved flow of chromatography of signal of telecommunication time change, also referred to as chromatogram。Namely appearance time according to chromatographic component peak measures retention, can carry out chromatographic qualitative analysis；Peak area or peak height are then relevant with the content of component, are used for chromatographic quantitative analysis。
In existing Chinese liquor, the ethyl acetate in Chinese liquor and ethyl hexanoate can not be effectively measured by the mensuration system of ethyl acetate and ethyl hexanoate, complicated operation, calculate inconvenience, need to measure correction factor, be unsuitable for automatically analyzing。
Summary of the invention
Technical problem to be solved in the utility model is to provide the mensuration system of ethyl acetate and ethyl hexanoate in a kind of Chinese liquor, ethyl acetate in Chinese liquor and ethyl hexanoate can be effectively measured by it, and simple to operate, convenience of calculation, do not need to measure correction factor, be suitable to automatically analyze。
This utility model solves above-mentioned technical problem by following technical proposals: the mensuration system of ethyl acetate and ethyl hexanoate in a kind of Chinese liquor, it is characterized in that, it includes microsyringe, gasifier, sample flow meter, radiator valve, carrier gas flux meter, piezometer, pressure regulator, carrier gas drying tube, carrier gas steel cylinder, chromatographic column, gas chromatograph, display screen, flame ionization ditector, microsyringe is connected with gasifier, gasifier is connected with one end of chromatographic column by sample flow meter, carrier gas steel cylinder, carrier gas drying tube, pressure regulator, piezometer, carrier gas flux is sequentially connected with, carrier gas flux meter is connected with one end of chromatographic column, the other end of chromatographic column and gas chromatograph, flame ionization ditector is connected, gas chromatograph, flame ionization ditector is all connected with display screen, sample flow meter and chromatographic column are all located in radiator valve。
