Abstract

L'invention concerne un procédé permettant de déterminer la concentration d'un constituant dans un système de dosage placé dans un tube capillaire. La lumière émise par ce système de dosage est proportionnelle à la quantité du constituant à doser. La lumière émanant du système est détectée et quantifiée et la détection est effectuée sensiblement à partir de la direction longitudinale du tube capillaire.
