    摘要： In a reagent strip for the dry-chemical detection of a component of an aqueous sample solution comprising a detection reagent in a membrane, the improvement wherein the membrane is an essentially anhydrous, but water-absorbing, membrane for a reagent substrate in an analytical agent for the dry-chemical detection of a component of an aqueous sample solution, comprising at least one hydrophobic film-forming, water insoluble organic polymer in which at least one hydrophilic organic polymer is dispersed as discrete particles. The reagent can be incorporated into the membrane when produced or can later be applied as by impregnation. The membrane performs as well as or better than multi-layer strips.
