Description

A dry reagent colorimetric test system for determining analytes in sample solutions containing interfering colored materials is presented comprising a reagent impregnated matrix containing a chromogenic material responsive to the analyte being detected and a masking dyestuff for obviating the interference caused by the colored materials thus allowing a proportional visual estimation of the response of the chromogenic material due to the amount of analyte in the sample solution.

Cette invention se rapporte à un système d'analyse colorimétrique à réactif sec conçu pour le dosage d'analytes dans des solutions échantillon contenant des matières colorées brouilleuses. Ledit système comporte une matrice imprégnée de réactif contenant une matière chromogène sensible à l'analyte à détecter et un colorant de masquage conçu pour empêcher le brouillage provoqué par les matières colorantes, ce qui permet d'effectuer une évaluation visuelle proportionnelle à la réaction de la matière chromogène liée à la quantité d'analyte présent dans la solution échantillon.
