摘要
An apparatus and also a method for calibration of a spectrometer for the measurement of spectral fractions of a substance (4) as a part of chemometry or chemometric processes are proposed, with a spectrometer device (1) for measuring of spectral fractions of the substance (4) to be analysed, and also with a calibration unit (2) used to carry out a calibration of the spectrometer device and/or of the measured data on the basis of measured spectrometric data, characterized by the following steps: a) measuring the totality of spectral fractions X and/or of associated substance concentrations of the substance (4) under analysis; b) Saving the totality of measured spectral fractions X in a memory module (3) as spectrometric measured data in the form of a multi-dimensional coefficient vector; c) From the totality of measured spectral fractions X, automatic extraction of spectral fractions Xrel physically relevant to the particular measuring process by means of an automatically running, iterative estimation method saved in the calibration unit (2); d) Calibration of the measured spectrometric data for the analysed substance (4) on the basis of spectral fractions Xrel of the spectrometric data extracted in step c) and which are physically relevant to the substance (4) under analysis.
