Abstract: Pipes provided with each switching valve in intermediate portions thereof for feeding sample solutions to a separation mechanism are joined by a multi-way joint, to reach the separation mechanism through a pump. When all valves are closed while driving the pump and thereafter one valve is opened, all bubbles etc. downstream the opened valve are swept and eliminated due to abrupt flow of a liquid since a portion downstream the valve has been decompressed. In switching of a sample in sample measurement, a valve of a pipe for a completely measured sample is left open while a valve of a pipe for a next sample is opened, and then the valve of the pipe for the previously completely measured sample is closed after a while. Thus, pressure fluctuation following sample switching is avoided.
