Abstract: A method determines an alcohol content of liquids that contain at least water and alcohol as well as sugar or similar substances, in the liquid. The liquid is located in an analysis cell is irradiated by an IR-LED light source, which emits infrared radiation with λ=1000-1500 nm. The IR light absorption is measured at least two different wavelengths, and the measurement values are converted into data on the alcohol content of the liquid. The liquid is irradiated with a first IR radiation with a wavelength λ1, where the absorption coefficient of the alcohol, and the absorption coefficient of the water, are identical in magnitude, and with at least a second IR radiation with a wavelength λ2, where the absorption coefficients and are different. The absorption measurement values determined by an IR detector are applied to a calculating unit for the calculation of the alcohol content.

Abstract: A method for spectroscopically determining the concentration of alcohols with 1 to 5 carbon atoms, especially ethanol, in liquid probes, especially alcohol-containing food products, healing preparations, cosmetic products and the like. The absorption of light by the probe is measured at at least one wave length in the range of 1100 nm to 1300 nm, and preferably in the range of 1150 nm to 1250 nm. The alcohol concentration is determined from the measured absorption with the help of a calibration. The alcohol content of a liquid probe can be determined in a simple and fast manner and over a large concentration range.
