DIFFERENTIAL SCANNING CALORIMETRY (DSC)

What is DSC?

DSC is a thermal analysis technique that measures the energy absorbed or emitted by a sample as a function of temperature or time.  When thermal transition occurs in the sample, DSC provides a direct calorimetric measurement of the transition energy at the temperature of the transition. 
DSC is often used to characterize the thermal transitions in polymers such as the glass transition temperature (Tg) and melting point (Tm).  Organic liquids or solids, and inorganics can also be analyzed.
