Summary:To provide a coolant introduction device and gas chromatograph equipped with the coolant introduction device that make it possible to accurately adjust temperatures of cooling objects.SOLUTION: A control unit 33 includes a temperature prediction processing unit 331. The temperature prediction processing unit 331 is configured to predict time differential information 322 in a storage unit 32, and a temperature inside a column oven 3 assuming that a coolant is supplied from a coolant supply part 8 on the basis of the time differential information 322. Thus, the temperature inside the column oven 3 when the coolant is supplied from the coolant supply part 8 can be accurately predicted by the temperature prediction processing unit 331. Further, in a case where the predicted temperature in the column oven 3 is a value suitable for an analysis action, when the coolant is supplied from the coolant supply part 8, the temperature inside the column oven 3 can be caused to be close to a proper temperature. Therefore, the temperature inside the column oven 3 can be accurately adjusted.SELECTED DRAWING: Figure 3 【課題】冷却対象の温度を精度よく調整することを可能にする冷媒導入装置、及び、当該冷媒導入装置を備えたガスクロマトグラフを提供する。【解決手段】制御部33は、温度予測処理部331を含んでいる。温度予測処理部331は、記憶部32の時間差情報322及び時間差情報322に基づいて、冷媒供給部8から冷媒を供給したと仮定した場合のカラムオーブン3内の温度を予測する。そのため、冷媒供給部8から冷媒を供給した場合のカラムオーブン3内の温度を、温度予測処理部331によって精度よく予測できる。そして、その予測したカラムオーブン3内の温度が、分析動作に適した値である場合に、冷媒供給部8から冷媒を供給すれば、カラムオーブン3内の温度を適切な温度に近づけることができる。そのため、カラムオーブン3内の温度を精度よく調整することが可能になる。【選択図】 図3
