The work demonstrates a powerful method of data analysis based on algorithms of mathematical gnostics and shows its application for evaluation of experimental heat capacity data. The method was first used during the initial setup and testing the functionality of a newly bought calorimeter. The stability of the calorimeter was examined and the optimum heating rate was determined. The optimum is chosen in order to maximize the signal to noise ratio. It is estimated as a temperature rate where the values of heat capacities obtained in repeated measurement have narrowest tolerance interval and narrowest interval of typical data. Heat capacities of three ionic liquids were further measured in the temperature range of 20–75 °C and repeatability analyzed by algorithms of mathematical gnostics. The width of the interval of typical data is less than 0.25 % in all cases
