Provided is a liquid vaporization system capable of promoting vaporization of a liquid material while solving a problem of residual liquid material. A liquid vaporization system has a liquid vaporization apparatus having a pump and a vaporizer. The vaporizer has a case, a heater provided inside the case, a heat storage plate heated by the heater, and a mesh. The mesh is formed by interweaving wires and has an overall flat plate shape. By overlapping the mesh on an upper surface of the heat storage plate, minute irregularities are formed on the heat storage plate by the mesh. A nozzle is provided above the mesh, whereby the liquid material is dropped from the nozzle onto the heat storage plate. The liquid material spreads over the heat storage plate in a thin film and is heated and vaporized on the upper surface of the heat storage plate.

The invention provides a vacuum control valve configured to control the vacuum pressure in the vacuum chamber. The vacuum control valve includes a control valve main body, an operation unit, a cylinder, a biasing unit, and a bellofram. The operation unit and the cylinder include a valve opening manipulation chamber and a shutoff load generation chamber. The shutoff load generation chamber is configured to have a common axial center line with the valve opening manipulation chamber and to generate a load applied to the operation unit in a direction for reducing the lift in accordance with a supply of the working fluid. And the shutoff load generation chamber may be formed in an interior of the rod.

This invention provides a sample injector for injecting a fixed amount of a sample into a mobile phase medium and discharging the mobile phase medium with the sample. The sample injector includes a first member having a medium passage for supplying the mobile phase medium and a sample passage for supplying the sample and a second member having a discharge passage for discharging the mobile phase medium with the sample to an outside of the injector. The second member is provided in contact with the first member. The first member and the second member are configured to move to a sample charging position and a sample injection position. The sample charging position is for the sample chamber to connect with the sample passage. The sample injection position is for the sample chamber to connect with the medium passage and the discharge passage.
