Radiochemical separations of metal lons by liquid-liquid chromatography were carried out on 2-cm long minicolumns packed with 4 to 6 ..mu..m porous silica microspheres containing 25 to 30 weight percent of 1.5 F di(2-ethylhexyl) phosphoric acid in dodecane. Column performance was evaluated using the elution of both tracer and macro quantities of Eu(III). Plate heights for tracer scale elutions were 0.015 to 0.025 mm and 0.05 to 0.07 mm at v = 2 and 30 cm/min, respectively. The separation of certain dipositive metal ions, tripositive lanthanide lons, and tripositive transplutonium lons were studied using the high efficiency minicolumns.
