Abstract

Dispositif utilisé pour déterminer la quantité de matière contaminante ou polluante présente dans un échantillon de liquide. Le dispositif comprend un système de conditionnement qui change les propriétés chimiques de l'échantillon de liquide de manière à faciliter la détermination ou la mesure d'une espèce présélectionnée, un système réducteur qui réduit l'espèce devant être détectée, ainsi qu'une sonde qui détermine la quantité de ladite espèce dans la solution. La nature du système de conditionnement de la solution du système réducteur et de la sonde peut être modifiée de manière à pouvoir effectuer la détermination de n'importe quelle espèce présélectionnée. Cette invention concerne également la maintenance d'une sonde par modification sélective des propriétés d'une sonde, cette modification se caractérisant par l'altération d'une surface de la sonde pour maintenir l'intégrité de cette dernière.
