Abstract
A method of operating a differential scanning calorimeter wherein errors in the heat flow rate measurement are reduced by operating the calorimeter in a quasiadiabatic mode and by employing a heat flow rate measurement algorithm that includes the leakage heat flow rate. The temperature of the DSC enclosure is controlled independently of the temperature of the measuring system, which allows the temperature difference between the sample and reference containers and the enclosure to be minimized, thus minimizing leakage heat flow.
