In an effort to obtain improved sensitivity in scanning unidimensional radiochromatograms of compounds labeled with weak beta-emitters, a detecting system was devised which simultaneously scans the upper and lower surfaces of the chromatogram. The instrument embodies substantial improvements based on the operation of a prototype.
