Differential Scanning Calorimetry (DSC)
  

Working Principles

  

DSC – Differential Scanning Calorimetry is a technique in which the difference in the amount of heat required to increase the temperature of a sample pan and reference pan  are measured as a function of temperature. Reference and sample pan, both 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 reference sample should have a well-defined heat capacity over the range of temperatures to be scanned.

The main application of DSC is in studying phase transitions, such as melting, glass transitions, or exothermic decompositions. These transitions involve energy changes or heat capacity changes that can be detected by DSC with great sensitivity.
