Abstract: A gas monitoring device for gas chromatograph, comprising a pump configured to take a gas out of a space in a column oven of the gas chromatograph (GC); a measurement flow path through which the gas taken out of the space in the column oven by the pump flows; a gas sensor having a sensing unit exposed in the measurement flow path, the gas sensor being configured to detect a specific component in the gas flowing through the measurement flow path; a flow rate detection unit including a self-heating element arranged in the measurement flow path, the flow rate detection unit being configured to acquire a signal corresponding to a flow rate of the gas flowing through the measurement flow path by controlling a voltage applied to the self-heating element so that the temperature of the self-heating element is set to a reference temperature; a temperature acquisition unit configured to acquire temperature information about the gas flowing into the measurement flow path; and a controller configured to control operations of the pump and the flow rate detection unit, wherein the controller is configured to set the reference temperature of the self-heating element of the flow rate detection unit to a temperature of the gas flowing into the measurement flow path based on the temperature information acquired by the temperature acquisition unit and determine normality of the operation of the pump based on the signal acquired by the flow rate detection unit. wherein the controller is configured to set the reference temperature of the self-heating element of the flow rate detection unit to a temperature of the gas flowing into the measurement flow path based on the temperature information acquired by the temperature acquisition unit and determine normality of the operation of the pump based on the signal acquired by the flow rate detection unit.

Abstract: A vial supply system is provided with: a sampler configured to supply a vial to a predetermined supply destination by a transport arm; a management device communicatively connected to the sampler, the management device being configured to manage a supply operation of the vial by the sampler; and a display device provided so as to be able to communicate with the management device. When a teaching mode for performing teaching for setting a position of a transport arm at the time when a transport arm of the sampler transports the vial to and from the supply destination is started, the management device is configured to cause the display device to display an operation to be performed by a user in the teaching.
