Abstract (en)

[origin: WO0148458A1] The invention relates to a method and a device for the online analysis of mixtures of substances in liquid form, using near infra-red spectroscopy (NIRS). According to said method, for an evaluation which uses a comparison of spectral data, only the binary mixtures of possible constituents are used in quantitative gradations as calibration spectra. In order to accelerate the evaluation process, all data points of a spectrum are totalled and each spectrum is characterised using a single characteristic number.
