<p>A calorimeter and a method of performing calorimetric analysis are disclosed. The calorimeter comprises a sample chamber having a gas inlet and a gas outlet, a flow duct interconnecting the gas inlet and the gas outlet to form a flow circuit with the sample chamber. A pump is disposed within the flow circuit operable to cause gas to flow into the gas inlet. There is a heater to heat gas flowing within the flow circuit. There is a respective sensor, operable to detect the temperature of one or more sample within the sample chamber. For use, the flow circuit is sealed such that gas within it is retained for circulation by the pump, the gas being heated by the heater before passing into the sample chamber to transfer heat to sample therein. In the method, one or more sample is placed in the sample chamber. The pump and the heater are then operated, while the output of the sensor is monitored to record the change of temperature of the sample over time.</p> |
