Abstract: Provided is a liquid injection device capable of accurately detecting whether a vial is mounted on the mounting portion with an inexpensive configuration. A sensor has a light-emitting part and a light-receiving part and is configured to emit light from the light-emitting part to pass through at least a part of a cylindrical cap attached to the vial to be mounted on a mounting portion and detect an amount of light received by the light-receiving part. An optical axis of the light from the light-emitting part to the light-receiving part is shifted or inclined in a direction that increases a distance that the light passes through the cap relative to a position where the optical axis of the light passes through the center axis within a plane perpendicular to the center axis of the cap.

Abstract: A GC assistance device includes a saving amount evaluator, a consumption amount evaluator and an outputter, and is used together with a gas chromatograph. The saving amount evaluator evaluates a saving amount of a resource caused by stopping of the gas chromatograph. The consumption amount evaluator evaluates a consumption amount of the resource caused by recovery of the gas chromatograph from a stop state. The outputter presents an evaluation value in regard to the saving amount and the consumption amount to a user. Alternatively, the outputter controls an operation state of the gas chromatograph based on the evaluation value.

Abstract: At least one of method information representing an analysis execution method to be used for analysis of a sample and device information for specifying the configuration of an analysis device is acquired as analysis information by an analysis information acquirer. Syringe information for specifying the configuration of a syringe is acquired by a syringe information acquirer. Based on the analysis information and the syringe information, whether the syringe is suitable for analysis of the sample is judged by a judge. The result of judgement by the judge is presented by a presenter.

Abstract: In a sample vaporization chamber, a liquid sample is vaporized therein to produce a sample gas. A split flow path is configured to discharge the sample gas in the sample vaporization chamber. A valve is provided in the split flow path and opens/closes to adjust a flow rate of the sample gas flowing through the split flow path. A filler material is provided at a filling position in the sample vaporization chamber or in the split flow path. The controller is configured to control a degree of opening of the valve so that when the sample gas in the sample vaporization chamber is discharged from the split flow path, a pressure in the sample vaporization chamber decreases at a pressure gradient smaller than a pressure gradient at which the filler material is displaced from the filling position.
