Abstract :	[en] The invention relates to a method of analyzing spectral data for the selection of a calibration model relating spectra of a substance to a physical or chemical parameter of the substance over a predetermined range of the physical or chemical parameter, comprising the steps of capturing spectral data of the substance with respective values of the physical or chemical parameter over the predetermined range, applying a plurality of calibration models and mathematical pretreatments to the captured spectral data in dependence upon the values of the physical or chemical parameter, calculating tolerance intervals and a reference level for each calibration model, and displaying the tolerance intervals and the reference level over the predetermined range for each calibration model. In this way, a possibility for analyzing spectra data is provided which is useful in spectroscopic applications and makes analytical interpretation and evaluation easier and more accurate.
