摘要： In a test strip for the detection of a component in a liquid sample, the strip comprising a support layer, a microporous polymer layer and a reagent for the detection of the component to be determined, the improvement wherein the microporous polymer layer is a membrane which has an asymmetric pore structure with the narrower pores being on the side to which the sample is applied, and the support layer is macroscopically smooth. The porous membrane is produced by coagulation from solution.

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.
