Ultrasonic direct fixing of reagent layer and method for preparing peel type test piece

摘要

A method for fixing a reagent layer directly onto a supporting base plate in the preparation of a dry analysis kit for determining a specific component in a liquid specimen wherein at least one of the reagent layer and the base plate is a thermoplastic resin, and which comprises the steps of: placing the reagent layer in contact with the base plate and externally applying ultrasonic vibration and pressure to the two layers to generate frictional heat thereby to melt the surface of the thermoplastic resin; applying pressure to make the molten surface of thermoplastic resin bite the non-thermoplastic material or to integrate the surfaces of thermoplastic layer and base plate; and removing the ultrasonic vibration and pressure.
