A new method of full deconvolution of the instrumental coefficients in scanning calorimeter of heat flux type has been proposed, including reasonable determination method of the thermal contact resistance between the sample pan and its stage. The determination utilizes the response of dynamic heat capacity obtained by temperature-modulated (T-M) mode of a commercial differential scanning calorimeter used as a single calorimeter. By taking into account of the contribution of heat exchange with purge gas, an extension of standard modeling has been proposed for the evaluation of the instrumental coefficients. An alternative method bypassing the full deconvolution is also proposed. (c) 2005 Elsevier B.V. All rights reserved.
