Various methods of preparing standards for activation analysis have been reported in the literature. This paper describes
the feasibility of preparing ion exchange resin based standards containing predetermined levels of ions. Using a solution
of known initial concentration of the ion, and given the value of its distribution coefficient, it is possible to predict
the resin concentration that will be obtained. Resins containing ppm levels of copper and manganese have been prepared and
their stabilities evaluated over a period of time. The feasibility of preparing a multielement standard has been studied with
five rare earth elements (La, Ce, Sm, Eu and Dy).
