Abstract
A target component is collected using a preparative separation and purification device having a holder for holding a trap column in which the target component has been captured, a liquid feeder for feeding a first solvent having compatibility with the water remaining in the trap column and a second solvent having low compatibility with water and high compatibility with the first solvent into the trap column, a flow-path switch for connecting the exit end of the trap column to a waste liquid flow path and a collection flow path, and a control unit for controlling the flow-path switch so that solution including water flows into the waste liquid flow path.
