METHOD OF DETERMINING THYROXINE METHOD OF DETERMINING THYROXINE

摘要

Method for the determination of thyroxine in biological fluids by adsorption on a cation exchanger, subsequent washing out of the interfering components, eluting the adsorbed thyroxine, liberating the iodine therefrom, and then carrying out the iodine determination in a conventional manner, which process is characterized by the use of an eluent, optionally together with a basic buffer, which destroys amino groups and liberates iodine from the thyroxine into the eluate.
