(3) spectral analysis, analyzes absorption spectra and the transmission spectrum of sample and standard solution and industrial spirit respectively, and the absorption spectra of sample and standard solution and edible alcohol and transmission spectrum and Strength Changes situation, whether judgement sample mixes industrial spirit.
Be specially: the solution of sample thief is in cuvette, then the edible alcohol solution getting the number of degrees identical with sample is in cuvette, prepare pure industrial spirit and pure edible alcohol is placed in cuvette simultaneously; Cuvette is put into UV, visible light near infrared spectrometer, arrange detector gap for " 8 ", wavelength, at 200nm-1400nm, measures testing sample respectively, with sample same concentrations standard solution, and the absorption spectra of industrial spirit and edible alcohol and transmission spectrum; Spectral analysis, analyzes absorption spectra and the transmission spectrum of sample and standard solution and industrial spirit, the absorption spectra of sample and standard solution and edible alcohol and transmission spectrum respectively; Sample is identical with transmission peaks with the absorption peak of transmission spectrum with the absorption spectra of standard solution, and intensity does not have broken line region, and sample has standard absorption peak and the transmission peaks of edible alcohol, and detecting sample is without the true wine product of industrial spirit.Sample is different with transmission peaks with the absorption peak of standard solution, and intensity has broken line region, and sample has industrial spirit point standard absorption peak and transmission peaks, detects sample for mixing industrial spirit fake wine product.
Further, the preparation of described sample, get a testing sample in cuvette, configure the standard edible alcohol solution identical with the testing sample number of degrees as standard solution, get pure industrial spirit and pure edible alcohol, industrial spirit is 99.5% ethanol+0.5% methyl alcohol, and edible alcohol is 95% brewage ethanol+5% water.
Further, described photometer spectral detection, computer uses UVProbe2.33 software to connect UV, visible light near infrared spectrometer, and spectral detection gap is " 8 ", and spectral detection wavelength coverage is 200nm-1400nm.
Further, described spectral analysis, the first absorption spectra of comparative sample and standard solution and transmission spectrum, if identical, then contrast the absorption spectra of edible alcohol and the standard absorption peak of transmission spectrum and transmission peaks, if identical, for without the true wine product of industrial spirit.If different, for mixing industrial spirit fake wine product; The absorption spectra of comparative sample and standard solution and transmission spectrum, if different, for mixing industrial spirit fake wine product.
Principle of work of the present invention is: extract a collection of testing sample, and unlatching computer and UV, visible light near infrared spectrometer normally work; The edible alcohol standard solution of configuration and sample same concentrations, extracts pure industrial spirit and edible alcohol; Measure absorption spectra by UV, visible light near infrared scene photometer and drink transmission spectrum and Strength Changes; Analyze absorption spectrum and the projection absorption peak of spectrum and transmission peaks and Strength Changes situation, draw the testing result of sample detection.
Technique effect of the present invention is: can detect by the method the fake wine product whether wine product mix industrial spirit; Low to the detection loss of detected sample; The accuracy of detection of detection method is high, and testing result is accurate.
