Differential Scanning Calorimetry (DSC)

Basics

Schematic DSC thermogram
  • Thermal characterization technique for determination of enthalpy changes (endo- and exothermic) due to changes in physical and chemical properties of a material as a function of temperature or time
  • Samples with known masses are repeated heated and cooled, changes in heat flow can be  converted into Cp
  • Detetction of transitions such as melts, glass transitions, phase changes, and curing
