DSC: history, instruments and devices
A. Fortunato, Mettler Toledo, Italy
Abstract:
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 ...
