Abstract

Appareil et procédé d'analyse d'un courant effluent Ledit appareil comporte un tube de refoulement qui dirige un effluent d'un point situé au-dessous d'une goutte de mercure formée par une électrode appropriée verticalement vers le haut coaxialement à l'axe vertical de la goutte de façon qu'il s'écoule sans turbulence autour de celle-ci en établissant un très petit volume mort. Application à l'analyse polarographique de substances que contient l'effluent d'un appareil de chromatographie en phase liquide.
