Principle

In a measurement with differential scanning calorimetry a sample of the test item and a reference material (identical crucible without the test item) are subjected to the same controlled temperature program. The difference in the temperatures of the test item and the reference material is recorded and applying a calibration function converted to a heat flow signal. When the sample undergoes a transition involving a change in enthalpy (endothermic on melting or boiling), that change is indicated by a departure from the base line of the heat flow record.
