Abstract

Abstract Translated from German Die Erfindung betrifft im wesentlichen wasserfreie, jedoch Wasser aufnehmende Membran für Reagenzträgerschichten in analytischen Mitteln zum trockenchemischen Nachweis von Bestandteilen wäßriger Probelösungen, dadurch gekennzeichnet, daß die Membran ein oder mehrere hydrophobe filmbildende, wasserunlösliche organische Polymere umfaßt, in weichen ein oder mehrere hydrophile organische Polymere als diskrete Partikel verteilt sind. The invention relates essentially to water-free, but water-absorbing membrane for reagent support layers in analytical means for the dry chemical detection of components of aqueous sample solutions, characterized in that the membrane comprises one or more hydrophobic film-forming, water-insoluble organic polymers, in which one or more hydrophilic organic polymers are used discrete particles are distributed.
