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: Provided is a gas chromatograph device capable of appropriately determining that a temperature of an entirety of a heating target has stabilized after cooling the heating target in a column oven to a target temperature after a temperature-rising analysis. A gas chromatograph device capable of performing a temperature-rising analysis cools an inside of a column oven by a cooling mechanism. When a detection temperature by a temperature sensor for detecting a temperature of the heating target has reached a target temperature after the inside of the column oven has been cooled, the heating target is heated by a heater. Upon reaching of the detection temperature of the temperature sensor to the target temperature, it is determined whether or not the temperature of the entirety of the heating target has stabilized based on power consumption of the heater.
