Differential Scanning Calorimeter (DSC) is a thermal analysis device used to analyze the physical and chemical changes of a substance based on heat flows. This device measures energy changes during the heating or cooling of a sample and a reference material.
The basic working principle relies on comparing the heat absorbed or released by a sample during phase transitions with that of a reference material. During this measurement, the following parameters are recorded:
- Heat Flow: The energy difference between the sample and the reference.
- Temperature Difference: Monitors energy changes by measuring the temperature difference between the sample and the reference.
