Abstract
A principle for drawing the base line is given when determining the enthalpy of the first-order phase transition by experiments with classical differential thermal analysis, power-compensated differential scanning calorimetry and heat-flux differential scanning calorimetry. When the principle is applied to Mraw's model which is applicable to the three types of instruments, theoretically rigorous drawing of the base line is shown in the case when the heat capacity of the sample before and after transition is different. The enthalpy of transition is obtained from the area enclosed by the base line and the recorded trace.
