A new method of absolute heat capacity measurement was developed in the Department of Biological Systems Physics at the E. Andronikashvili Institute of Physics, Georgian Academy of Sciences. This is the method of absolute heat capacity measurement of the differential calorimetric ampoule sample and reference cell temperature difference registration while alternate transferring of heat pulses to the cells occurs. The new method makes possible to determine both the heat capacities of the sample and reference cells and the difference of thereof. The method of cell temperature difference compensation is used in order to decrease in the time of equilibrium establishment. The proposed method of absolute heat capacity measurement was implemented in the model of the virtual differential pulse calorimeter. The model allows to perform calculations of the design of the differential ampoule - the main part of any calorimeter.
