Abstract
Disclosed herein is a separation column comprising a porous block covered with a coating wherein space-free adhesion is attainable therebetween by low temperature process without releasing octadecylsilyl bases and others from the porous block. A monolith rodis covered with a metal or resin coating. Then, the monolith rodcovered by the coatingis further covered with a rod retainermade of a low melting point metal (melting point 100-200 degrees C.) to form a column body. Since the rod retaineris formed by pressure molding at low temperature (100-200 degrees C.). It is therefore possible to absorb the surface irregularities of the monolith rodby the coatingwhile octadecylsilyl bases and others from are released when the retaineris formed. This allows the potential separation ability of the porous block to be brought out maximally.
