  • Patent number: 6820013
    Abstract: The invention relates to a method and an apparatus for the on-line analysis of liquid substance mixtures by means of NIRS. For evaluation by spectral data comparison, merely the binary mixtures of the possible components in quantitative graduations are used as calibration spectra. In order to accelerate the evaluation, all data points of a spectrum are summated, and each spectrum is characterized by only one characteristic number.
