Abstract
In a preparative separation-purification system for passing a solution containing a target component through a trap columnto capture the target component in the column, and for subsequently passing an eluting solvent through the columnto elute the captured component and collect it in a container, an outlet apertureof the columnhas a tapered shape whose sectional area is largest on a plane facing an inner space of the columnand decreases in the flowing direction of the liquid. A filterfor preventing deposition of the target component is also provided at the boundary between the inner space of the columnand a passage for discharging liquid from the inner space. By this configuration, clogging of the passage at the outlet end of the columndue to deposition of the target component is prevented.
