ABSTRACT:
A multilayer element for the analysis of a liquid containing an analyte comprising a reaction layer which retains a predetermined amount of a diffusible reagent containing a detectable species; said reagent adapted to be rendered substantially non-diffusible by said analyte as a function of the concentration of said analyte; a registration layer adapted to receive reagent diffusing thereto; means for detecting said reagent in said registration layer and an insulating layer intermediate said reaction layer adapted to provide discrimination between detectable species in said reagent layer and said registration layer.
