Abstract

Procédé et dispositif pour mesurer la concentration d'un composé de faible poids moléculaire dans un milieu complexe, ce milieu étant introduit dans un dialyseur 3 dont la sortie est envoyée vers une unité de mesure 19 par l'intermédiaire d'un lit d'enzymes 17. Pour obtenir une valeur zéro dépendant d'autres facteurs dans le milieu complexe, le dialysai est envoyé directement vers l'unité de mesure 19, passer par le lit d'enzymes. Application notamment à la dialyse du sang.
