A system and method to improve the accuracy of the measure of constituent element(s) in a sample containing domains potentially including the constituent element(s) are described herein. For each domain, the volume of the domain is estimated and the concentration of the constituent element(s) in the domain is determined using LIBS. When all the domains have been analyzed, the volumetric concentration of the domains is summed and divided by the total volume of the sample. Accordingly, by limiting the concentration analysis to separate domains, it is possible to improve the accuracy of the concentration analysis.
L'invention a pour objet un procédé et un système permettant d'améliorer la précision de la mesure d'un ou de plusieurs composants dans un échantillon contenant des domaines incluant potentiellement le ou les composants. Pour chaque domaine, on estime le volume du domaine et on détermine la concentration du ou des composants dans le domaine par LIBS. Lorsque tous les domaines ont été analysés, la concentration volumétrique des domaines est additionnée puis divisée par le volume total de l'échantillon. Ainsi, en limitant l'analyse de la concentration aux domaines distincts, il est possible d'améliorer la précision de l'analyse de la concentration.
