Abstract

L'invention concerne un système d'analyse équipé d'un terminal comprenant une partie d'acquisition d'élément permettant d'acquérir la teneur d'un élément contenu dans un objet dans un réservoir d'électrolyse, et un serveur comprenant un récepteur permettant de recevoir la teneur de l'élément acquise par la partie d'acquisition d'élément, et une partie d'analyse d'état permettant d'analyser l'état de l'objet en fonction de la teneur de l'élément reçu en provenance du récepteur. Le réservoir d'électrolyse peut comprendre une membrane échangeuse d'ions, et une chambre d'électrode positive et une chambre d'électrode négative séparées par la membrane échangeuse d'ions. Une solution aqueuse d'un chlorure de métal alcalin ou une solution aqueuse d'un hydroxyde de métal alcalin peut être introduite dans la chambre d'électrode positive, et une solution aqueuse d'un hydroxyde de métal alcalin peut être extraite de la chambre d'électrode négative. La partie d'analyse d'état peut : analyser l'état de l'objet en fonction d'une première relation prédéfinie entre l'efficacité en cours du réservoir d'électrolyse et la teneur de l'élément, analyser l'état de l'objet en fonction d'une deuxième relation prédéfinie entre la tension du réservoir d'électrolyse et la teneur de l'élément, ou analyser l'état de l'objet en fonction d'une troisième relation prédéfinie entre la concentration en ions chlore dans la solution aqueuse de l'hydroxyde de métal alcalin et la teneur de l'élément.
