Abstract:
A method for preparing a peel type test piece for dry analysis for determining a specific component in a liquid specimen comprising a support base plate having thereon a reagent layer comprising a porous matrix impregnated with a reagent and further having thereon a releasable film layer having a function of filtering out corpuscles, the releasable film layer being to be stripped after application of a specimen to observe coloration of the reagent layer, wherein the support base plate, the reagent layer and the releasable film layer are bonded to each other in a streaky manner, or at a plurality of discrete points, which method consists essentially of the steps of:superposing the reagent layer and the film layer on the supporting base plate in this order in mutual contact and applying ultrasonic vibrations from the supporting base plate side;applying pressure to make the surface of a molten layer encroach and bond to the surface of an adjacent non molten layer in a streaky manner or at a plurality of discrete points or to integrate the surface material of a molten layer with the surface of an adjacent layer in a streaky manner or at a plurality of discrete points; andremoving the ultrasonic vibrations and pressure.
