Differential scanning calorimetry (DSC) measures the difference between the heat flow to the sample and the reference pan that flows undergo with a controlled temperature program. Heat flow corresponds to transmitted power and is estimated in watts (W). The change in enthalpy after absorbing the energy is term as an endothermic reaction and when the sample releases the energy is termed as an exothermic reaction.
Different thermal events measured by DSC such as crystallization, the onset of oxidation, melting, cure reaction, and heats of transitions i.e. enthalpy.
