Differential scanning calorimetry (DSC)

In differential scanning calorimetry (DSC), the difference in heat flow between sample and reference sensors is measured as a function of temperature. 

DSC can be used to study phase transitions such as melting, crystallization, cold crystallization or glass transition, as well as heat capacity. This versatile thermal analysis technique may be used to study cure and crystallization kinetics, and to determine material purity. It provides information on processing effects and material fingerprinting characteristics. Numerous DSC techniques are offered by Arkema Analytical Solutions across a broad range of temperature conditions to provide information about:


  • Material fingerprinting
  • Melting point and glass transition
  • Curie point
  • Crystallization and degree of crystallinity
  • Mesophase transitions including liquid crystals
  • Melting point depression analysis
  • Heat of fusion
  • Curing
  • Decomposition analysis
  • Purity determination


Our experts' focus is on the latest DSC techniques and specialized instruments such as modulated DSC and pressure DSC.
