Abstract
A solvent delivery device includes a solvent delivery pump and a flow path switching valve. The flow path switching valve is connected to downstream ends of mobile phase sending flow paths and the solvent delivery pump is to be connected to one of the mobile phase sending flow paths by switching the flow path switching valve. At least one of the mobile phase sending flow paths includes a buffer solution sending flow path. The buffer solution sending flow path includes a butler solution storage section, a cleaning solution storage section, and a mobile phase switching valve for switching connection of the flow path switching valve to one of the storage sections.
