ABSTRACT:
A filler for separating an optical isomer comprising a surface-hydrophobic filler component and an optically active lipophilic crown compound carried on the filler component by adsorption. The filler may be charged in a column to carry out separation of a sample such as amino acid or the like in the form of an aqueous solution.
