Abstract

Système de mesure multiple destiné à l'analyse électrochimique de liquides et gaz en voie d'écoulement et comprenant plusieurs détecteurs sélectivement sensibles et une électrode de référence, lesquels sont contigus à des chambres de mesure qui, parcourues successivement par le fluide à analyser, sont réalisées chacune sous forme d'un évidement accessible à partir de la surface d'un corps isolant. Les corps isolants 51 sont sensiblement cylindriques et présentent des canaux d'amenée et de sortie centraux 58, 59 ainsi qu'un trou radial 61 au fond duquel est formée chaque fois une chambre de mesure 60. L'invention est applicable par exemple à l'analyse électronique/enzymatique de molécules organiques dans des milieux aqueux.
