摘要：
Porous styrene-divinylbenzene copolymer particles having SO.sub.3.sup.- groups and counter ions for SO.sub.3.sup.- groups, said counter ions being (a) at least one of Ca.sup.++ and Sr.sup.++ and (b) at least one of Pb.sup.++ and Ba.sup.++ and the equivalent ratio of (a)/(b) being 1/2 to 2/1, are an excellent liquid chromatographic column packing material suited for separating sugars different in kind but the same in molecular weight.
