METHOD AND APPARATUS FOR SPECTROSCOPIC ANALYSIS, IMPLEMENTNG INFRARED AND FLUORESCENCE MULTICHANNEL PROCESSING OF SPECTRAL DATA

摘要

Method for analysing at least one sample, implementing a method for analysing spectroscopic data based on a multiway statistical model, characterised in that it comprises: a) the illumination of said or of each sample to be analysed by a first light source and by a second light source, said at least one second light source being separate from said first light source; b) the acquisition of fluorescence spectrums from said or from each sample, said fluorescence spectrums resulting from the illumination of said or of each sample by one or more light beams emitted by said first light source; c) the acquisition of transmittance and/or reflectance spectrums from said or from each sample, said transmittance and/or reflectance spectrums resulting from the illumination of said or of each sample by one or more light beams emitted by said second light source; d) the organisation of said fluorescence spectrums acquired into a first acquisition data cube; e) the organisation of said transmittance and/or reflectance spectrums into a second acquisition data cube; f) the amalgamation of acquisition data of said first cube and acquisition data of said second cube into a third amalgamated data cube; g) the decomposition of the amalgamated data from said third cube by applying said multiway statistical model; h) the determination of at least one indicator characterising said or each sample, from the data coming from applying said multiway statistical model to said amalgamated data. Device for the implementation of such a method.
