When a signal for filling up with or substituting a mobile phase is externally transmitted to a control part, the control part switches a valve for connecting a channel from a pump part to a sampling needle through a sampling loop and moves the sampling needle toward a drain port. Thus, a channel is formed through a mobile phase container.fwdarw.a pump.fwdarw.the valve.fwdarw.the sampling loop.fwdarw.the sampling needle.fwdarw.the drain port.
