Abstract

Cette invention concerne un procédé et un appareil permettant d'évaluer la concentration d'une matière à analyser présente dans un échantillon, au moyen d'une analyse multispectrale effectuée dans les gammes d'infrarouge proche et d'infrarouge moyen. On utilise, pour analyser un échantillon, un rayonnement incident contenant une pluralité de régions distinctes, sans chevauchement, de longueurs d'onde comprises approximativement entre 1100 et 5000 nm. On détecte le rayonnement réfléchi de manière diffuse qui ressort de l'échantillon et l'on obtient une valeur représentative de la concentration de la matière à analyser en appliquant des techniques de chimiométrie. Il est possible d'effectuer une corrélation croisée entre les informations issues de chacune des régions de longueurs d'onde ne se chevauchant pas, dans le but d'éliminer les interférences d'arrière-plan.
