PURPOSE:To obtain a thermal analysis device with a gas analysis function without causing thermal decomposition and condensation of a generated gas to be generated in a gas conduit which carries the generated gas. CONSTITUTION:A thermal analysis device is provided with a protection tube 3 which surrounds a sample 10, a heater 5 which allows a temperature of the sample 10 to be changed, and a mass analysis device 2 which is connected to the protection tube 3 through a gas conduit 15. A gas conduit temperature- controlling device 21 which allows a temperature of the gas conduit 15 to be changed, a thermocouple 11 which detects a temperature of the sample 10, and a control device 12 which controls the gas conduit temperature-controlling device 21 based on a temperature detection result by a sample temperature detection means are provided. Then, a control device 12 controls the gas conduit temperature-controlling device 21 so that a temperature of the gas conduit 15 is equal to that of the sample 10. |
