Principles of method if other than guideline:

Method: Differential Scanning Calorimetry
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.
