Abstract
Collection containers (17) are heated by head conduction from a container rack (18) with a heater (19) as the heat source. When an eluting solvent is supplied into a trap column (7) by a pump (5), an eluate containing a target compound exiting from the column (7) flows through a preparative separation passage (13) and drips from a solution nozzle (13a), and this solution is separated into fine droplets by a gas stream blowing from a gas ejection nozzle (15a). When a droplet touches an inner wall of the container (17), the volatile solvent immediately vaporizes, leaving the target compound precipitated in solid forms on the inner wall. Thus, the process of vaporizing and drying the eluate to collect the target compound is completed within a short period of time. This process can be performed online and hence is suitable for laborsaving.
