Claims

[Scope of utility model registration request]

A port for inflowing the mobile phase from the tank, two ports for inlet and outlet to the sample loop that loads the injected sample, a port for injecting the sample from the syringe, and a port for draining the waste liquid bottle. A member provided with ports for flowing out into the column, and a groove that connects intermittently by relative rotation a state in which the sample is introduced into the column through these ports and a state in which the sample is loaded into the sample loop. In a sample injector comprising a member provided with a port for inflowing the mobile phase from the tank and a groove connecting to one port to the sample loop, it is also possible to connect to a port to a waste liquid bottle for draining. A sample injector characterized by a long groove.
