A radiochemical separation scheme for the determination of 25 neutron activated trace elements in biological soft tissue is represented. The scheme includes wet ashing and 16 different organic and inorganic ion exchangers. The procedure is semiautomatized and a description for manufactoring the non commercial available exchangers is given. Precision of the scheme is determined for each single element as well as for a mixture of all elements together.
