<p>INTEGRAL ELEMENT FOR ANALYSIS OF LIQUIDS The present invention concerns a multilayer element for the analysis of liquids which comprises, in the form of an integral arrangement, (1) a reagent layer including a composition comprising material that is reactive or otherwise interactive in the presence of a substance to be analyzed (analyte) to provide a diffusible, detectable species, and (2) a registration layer that is permeable to the detectable species and within which such species, e.g., a dye, can be detected. The element also includes a spreading layer, preferably separated from the registration layer by the reagent layer, to spread within itself at least a component of liquid applied to the element such that a uniform apparent concentration of a spread component (e.g., analyte) is provided to the reagent layer.</p> |
