The use of enriched Ca-48 is expected to improve the sensitivity of Ca-48 double beta decay measurements. We have studied the enrichment of Ca-48 with chemical exchange isotope separation using benzo-18-crown-6-ether resin. Chromatographic migrations of the calcium adsorption band were carried out at different migration lengths, 1 m, 20 m, and 200 m, using glass columns. Separation coefficients were observed as approximately 3 x 10(-3). Efforts have been made towards the production of benzo-18-crown-6-ether monomer at reasonable cost for the production of crown-ether resin for the separation of Ca-48.
