A product for the qualitative or quantitative analysis of substances in the aqueous liquid

摘要

P the invention relates to an analytical product for the determination of a component in an aqueous liquid. / p & & p & the product comprises a layer that is permeable to aqueous liquid and to the component to be assayed, in which are incorporated in the analytical reagents which one is the peroxidase and a hydrophobic copolymer comprising: 1 degrees of hydrophobic units, for example, alkyl acrylate units, 2 degrees of the anionic motifs, for example of the acid units alkanesulfonique, and 3 degrees of the methacrylate units 2 - acetoacetoxyalkyl. / p & & p & is performed with this copolymer of the analytical products which have good stability on storage, these products are used in particular to the proportions of constituents in body fluids, in order to establish the diagnostics. / p
