In DSC, the heat flow in and out of a sample and a reference material is measured as a function of temperature as the sample is heated, cooled, or held isothermally at constant temperature. The measurement signal is the energy absorbed or released by the sample in milliwatts. DSC can detect endothermic and exothermic effects, determine peak areas (transition and reaction enthalpies), determine temperatures that characterize a peak or other effects, and measure specific heat capacity. Since the end of the nineteenth century, DSC has been improved and optimized. With the numerous technological innovations, in both hardware and software, it can explore new and demanding applications. Different measurement principles, sensors, signal processing, accessories, and evaluation capabilities make differential scanning calorimetry one of the most common and versatile techniques in material characterization. Today DSC benefits from technological solutions used previously for other applications (MEMS technology, optical devices, and parameter estimation methods).
