  • Device for optically determining the concentration of alcohol and carbohydrates in a liquid sample
    Patent number: 10132787
    Abstract: Disclosed is a device for optically determining a concentration of alcohol and carbohydrates in a liquid sample. The device includes at least a first and a second light source arranged for exposing the liquid sample in a wavelength range between 750 nm and 1000 nm, a spectrometer arranged to determine a first and a second light intensity by measuring the light from the first and the second light source, a processing unit which is connected to the spectrometer and which is arranged to determine an absorption value of the liquid sample from a comparison of the first and the second light intensity with a reference value. In certain aspects, the device may further include a processing unit that calculates concentrations of alcohol and/or carbohydrates and at least two polarization filters.
