DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. Generally, the temperature program for a DSC analysis is designed such that the sample holder temperature increases linearly as a function of time. The technique was developed by E.S. Watson and M.J. O'Neill in 1962. Within TPM the DSC a Mettler Toledo DSC822^e  is used for many applications, e.g. heat of hydration processes, analysis of glass transition temperatures of coatings.
