Abstract:
A plurality of suctioning flow paths for suctioning mobile phases meet each other at a meeting portion. The meeting portion is connected to an inlet flow path communicating with an inlet of a reciprocating pump. The suctioning flow paths are respectively provided with solenoid valves for opening and closing the respective flow paths. The suctioning flow paths are respectively provided with orifices between the solenoid valves and the meeting portion. The orifices are sections of the respective suctioning flow paths having smaller diameters.
