Abstract

L'invention a trait au domaine de la chimie analytique. Elle concerne un support-réactif destiné à déceler la présence d'un constituant dans un échantillon liquide. Ce support-réacif comprend un élément de support ou substrat 1 auquel est attaché un élément indicateur qui produit une réponse apte à être décelée, par exemple un changement de couleur, en présence dudit constituant de l'éthantillon. L'élément indicateur comprend une couche sensible supérieure 3, une couche absorbante inférieure 2 et une couche d'arrêt 4 sensiblement imperméable à l'échantillon, entre les couches supérieure 3 et inférieure 2. L'élément indicateur est attaché au substrat par la face inférieure de la couche absorbante 2. Application à la mesure analytique de divers paramètres, notamment dans des échantillons de liquides biologiques.
