A method and system for spectrum data analysis. The method comprises the steps of collecting a spectrum of an unknown material; providing a set of element data templates; calculate optical least squares weights for the element data templates in approximating the spectrum; removing one or more of the templates having negative weights in approximating the spectrum; and re-calculating an approximation of the spectrum with said one or more templates removed.

Le procédé et système d'analyse de données spectrales de l'invention englobe les opérations suivantes: obtention du spectre d'une matière inconnue; obtention d'un ensemble de modèles de données d'éléments; calcul de pondérations de moindres carrés optiques pour les modèles de données d'élément lors de l'approximation du spectre; retrait d'un ou de modèles à pondérations négatives lors de l'approximation du spectre; et nouveau calcul de l'approximation du spectre après retrait d'un ou de modèles.
