Part 1 here deals with the origin of a dsc melting peak and derives the properties of an ideal melting peak Dsc is used to study the thermal behavior of new materials and to develop new materials with specific thermal properties In part 2, these ideas will be applied and illustrated with the aid of practical examples.

A dsc thermogram may look simple, but it holds rich information about your material’s thermal behavior
As you heat or cool the sample, the curve reveals how it absorbs or releases energy, helping you detect transitions like melting, crystallization, or softening.
In dsc, the difference in temperature (∆t) between the sample and an inert reference is maintained at zero as they are subjected to controlled heating or cooling. Thermogravimetric analysis, differential scanning calorimetry and evolved gas analysis coupled with a mass spectrometer. Differential scanning calorimetry (dsc), as it was mentioned above, is a method involving the measurement the difference of heat flow between a tested sample and a reference sample (standard, usually pure metals or sapphire), which is generated by the temperature control system. An alternative technique, which shares much in common with dsc, is differential thermal analysis (dta)
In this technique it is the heat flow to the sample and reference that remains the same rather than the temperature.
