Abstract:
1. The arrangement for calibrating a spectrometer for application in chemometrics or chemometric processes in the context of measuring spectral fractions of a substance to be examined, comprising: a spectrometric apparatus for measuring spectral fractions X of the substance to be examined; a calibration unit for calibrating the spectrometric apparatus; a memory module for storing measured and evaluated, spectrometric data; and a selection module, via which, based on a mathematical iteration method, physically relevant spectral fractions Xref of a measurement are automatically extractable, and said selection module is connected with said memory module and said spectrometric apparatus; said arrangement is adapted to store the totality of the measured spectral fractions X in said memory module as spectrometric measurement data in the form of a multidimensional coefficient vector; and said mathematical iterative estimation method comprises an iterative estimation method according to Bayes, via which coefficient values of the multidimensional coefficient vector tending toward zero during the iteration are removed before a regression analysis.
