Principles of method if other than guideline:

In a measurement with differential scanning calorimetry (DSC) 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 the original measurement signal which is internally assigned to the heat flow rate. The heat flux DSC belongs to the class of heat-exchanging
calorimeters. A defined exchange of the heat to be measured takes place via a thermal resistance. In contrast in the power compensation DSC, the
heat to be measured is compensated with electric energy, by increasing or decreasing an adjustable heating power.
When the sample undergoes a transition involving a change in enthalpy, for example an endothermic melting or boiling transition, that change is
indicated by a departure from the base line of the heat flow record. The peak area is proportional to the change in enthalpy.
