Abstract

La présente invention concerne un détecteur voltammétrique pour détecter une substance à analyser dans une solution. Le détecteur voltammétrique (100, 200, 300, 400, 500) selon un mode de réalisation de la présente invention comprend seulement deux électrodes. L'une des deux électrodes est une électrode de travail (101, 201, 301, 401, 501) et l'autre des deux électrodes est une contre-électrode (102, 202, 302, 402, 502). Cela correspond à une configuration à deux électrodes. Le rapport entre la surface active de la contre-électrode (102, 202, 302, 402, 502) et la surface active de l'électrode de travail (101, 201, 301, 401, 501) est égal ou supérieur à 20. Aucune électrode de référence n'est requise dans le détecteur voltammétrique, ce qui offre un moyen plus fiable de détection d'une substance à analyser dans une solution. De plus, la suppression de l'électrode de référence contribue à réduire le coût de production du détecteur voltammétrique. L'invention concerne également un procédé de détection de la substance à analyser dans une solution par le détecteur voltammétrique.
