Abstract
Procédé et dispositif pour diluer une solution concentrée, notamment en combinaison avec une analyse, la solution étant aspirée en même temps que le diluant, en direction d'un dispositif de pompage 8, 10 qui est conçu de manière à séparer ou isoler une quantité de melange qui correspond à la quantité de solution concentrée, tandis que le reste du mélange est envoyé vers une chambre de mesure 13 qui est conçue de manière à mesurer une quantité correspondante de diluant qui est alors mélangée avec la solution concentrée. Application notamment à une analyse de sang en continu.
