Abstract

L'invention concerne les techniques de mesure. Le dispositif faisant l'objet de l'invention est du type comprenant une chambre à courant de liquide 1 faisant partie d'un analyseur et comportant un orifice d'admission 2 et un orifice de sortie 3, et est caractérisé en ce que la deuxième fenêtre 9 de ladite chambre est exécutée sous forme d'un cylindre dont l'axe coïncide avec l'axe optique de l'illuminateur 4 et qui constitue les parois de ladite chambre. L'invention s'applique notamment à l'analyse de suspensions à faible concentration.
