Abstract

L'invention se rapporte aux mesures électrochimiques, en particulier à l'analyse voltampérometrique de la composition d'une solution et peut être utilisée dans les industries chimique, métallurgique et alimentaire et à des fins écologiques. Le dispositif de mesure électrochimiques de l'invention comporte une chambre de mesure sous forme de creux segmentaire à fente qui peut être à flux discret ou stagnant. Le corps est démontable, le plan de démontage étant disposé en parallèle à un plan longitudinal du creux de la chambre. Une électrode auxiliaire et une électrode de préparation de l'échantillon sont réalisées intégralement avec la chambre sous forme de revêtement superficiel éléctroconducteur des surfaces segmentaires du creux. L'invention vise à augmenter l'exactitude, la répétabilité et la reproductibilité des résultats d'analyse.
