Abstract

L'analyse en écoulement continu est effectuée sur des liquida que l'on dirige dans un conduit, le courant de liquide s'écoulant étant séparé par des bulles de gaz Le dispositif comprend un corps 11 traversé par un passage 12 constituant le conduit dans lequel s'écoule le courant liquide. Le tube 13 dont le diamètre extérieur est égal au diamètre du conduit 12 est inséré à une extrémité pour former une liaison d'entrée, et une section de tube 14 dont le diamètre est égal au diamètre du conduit 12 est inséré à une extrémité pour former une liaison d'entrée, et une section de tube 14 dont le diamètre est égal au diamètre du conduit 12 est introduite dans un contre-alésage du corps 11 pour former une liaison de sortie. Le tube 13 présente un alésage 15 de plus petite dimension que le conduit 12 et le tube 14 présente un alésage 16 ayant pratiquement la même dimension que le conduit 12. Applicable aux instruments d'analyse.
