Abstract

In a preparative separation-purification system for passing a solution containing a target component through a trap column to capture the target component in the column, and for subsequently passing an eluting solvent through the column to elute the captured component and collect it in a container, a dilution passage is merged with a collection passage for sending an eluate from the outlet end of the trap column to the collection container, and a diluting liquid is intermittently introduced through the dilution passage into the collection passage. The diluting liquid lowers the concentration of the target component in the eluate and impedes the deposition of the target component. Thus, clogging of the passage due to the deposition of the target component eluted from the trap column is effectively prevented.
