Method for determination of ethanol concentration in an aqueous solution containing an alcoholic beverage

Method for determination of ethanol concentration in an aqueous solution containing an alcoholic beverage

A method is described for determining from a measurement of fluorescence intensity the concentration of ethanol in water. This end is attained by obtaining data which establishes a relationship between an intensity of fluorescence in the spectral region 490-650 nm for a solution obtained by mixing a...

description A method is described for determining from a measurement of fluorescence intensity the concentration of ethanol in water. This end is attained by obtaining data which establishes a relationship between an intensity of fluorescence in the spectral region 490-650 nm for a solution obtained by mixing a fluorescent agent in a solvent, and an intensity of fluorescence in the spectral region 490-650 nm measured for a calibration sample obtained by mixing the fluorescent agent's solution with a water ethanol solution having a known concentration of ethanol.
