摘要：
The present invention is directed to reduce the dead volume in a flow path with trap functions. A flow path switching valve 1 is provided, which includes a rotor, i.e., rotor 3, and a housing top 9 having four ports 7a-7d connected to external flow paths, wherein two ports used for a mobile phase for analyzing are an inlet port 7a and an outlet port 7b, and the other two ports used for a mobile phase for condensing are an inlet port 7c and an outlet port 7d. In the rotor 3, two circular arc-shaped rotor trenches 11a, 11b for communicating two ports are formed at positions corresponding to the ports 7a-7d. The rotor trench 11b is filled with an adsorbent.
