What is Differential Scanning Calorimetry (DSC)?

DSC is a thermal analytical technique that determines the heat flow associated with a material’s physical or chemical transitions. It operates by heating or cooling a sample and monitoring the energy required to maintain a constant temperature difference between the sample and a reference material.

Principle of DSC Analysis

The fundamental principle of DSC involves:

1. Sample and Reference Comparison: A sample and an inert reference material are placed in separate pans within a controlled furnace.
2. Heat Flow Measurement: The instrument applies heat, and the difference in heat flow between the sample and reference is recorded.
3. Endothermic and Exothermic Transitions: The heat absorbed or released during melting, crystallization, or decomposition is analyzed.

The resulting DSC curve displays peaks corresponding to thermal events such as glass transitions, melting, and degradation.
