What is Differential Scanning Calorimetry (DSC)?
A thermal analysis technique that measures the heat flow into or out of a sample as a function of temperature or time. DSC is used to study phase transitions, melting points, glass transitions, and reaction enthalpies in materials science and pharmaceuticals.

A thermal analysis technique that measures the heat flow into or out of a sample as a function of temperature or time. DSC is used to study phase transitions, melting points, glass transitions, and reaction enthalpies in materials science and pharmaceuticals.
DSC is used for pharmaceutical polymorph characterisation and purity determination, polymer glass transition and melting behaviour, food analysis (fat crystallisation, starch gelatinisation), biomolecule stability (protein Tm), energetic material safety screening, and quality control of raw material…
DSC of energetic materials (explosives, propellants, peroxides) can reveal decomposition onset temperatures. Samples must be loaded carefully; high-pressure DSC pans are used for reactive samples. Thermal runaway detection by DSC is a key tool in chemical process safety.
The formula or notation for Differential Scanning Calorimetry (DSC) is: dH/dt = C_p × (dT/dt)
