Summary:PURPOSE:To make it possible to prepare an elution liquid with a predetermined concn. gradient extremely simply, by providing a first flow line guiding a start solvent at the time of gradient start and a second flow line guiding a finish solvent at the time of gradient finish from the storage tank thereof. CONSTITUTION:A predetermined start solvent A is accommodated in a pump. cylinder 2 and sent and supplied through a start solvent flow line 4 being a first flow line by operating the piston of the pump cylinder 2. On the other hand, the finish solvent B accommodated in a storage tank 6 is sent and supplied through a finish solvent flow line (second flow line) 8 by a quantitative emission type pump 10 provided to said flow line 8. By this constitution, an elution liquid with a predetermined concn. gradient can be prepared extremely simply.
