Abstract:
1. Method for spectroscopic analysis of at least one sample implementing a method for analysis of spectroscopic data based on a multi-way statistical model, which method includes: a) the illumination of said or of each sample to be analyzed by a plurality of excitation light radiations with respective wavelengths; b) the acquisition of front-face fluorescence spectra of said or of each sample, each corresponding to a respective excitation light radiation; c) a pre-processing of the fluorescence spectra acquired; d) for each sample, the calculation of a score vector by application to the pre-processed spectra of said multi-way statistical model, identified by a fluorescence excitation loading vector and by an emission loading vector; and e) the determination of at least one parameter chosen from a quality indicator of said or of each sample and a parameter characterizing a method to which said or each sample has been subjected, on the basis of said score vector; the method being characterized in that the average spectral gap between said excitation light radiation is at least 50 nm over a spectral range of at least 100 nm.
