Breakthrough chromatography was explored as a technique of separating the {sup 44}Ca and {sup 40}Ca isotopes of calcium. The solid phase utilized polymer-bound 18-crown-6 compounds. The effect of adding dimethylsulfoxide (DMSO) to the fluid phase solution of methanol and chloroform was found to increase the separation coefficient from 0.0025 {plus minus} 0.0003 to 0.0035 {plus minus} 0.0003. Robotic sample preparation increased the accuracy and efficiency of the system. 8 refs., 6 figs.
