Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature.Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature.
What does a differential scanning calorimeter do?
DSC is a thermal analysis apparatus measuring how physical properties of a sample change, along with temperature against time. In other words, the device is a thermal analysis instrument that determines the temperature and heat flow associated with material transitions as a function of time and temperature.
What is the basic principle of Differential Scanning Calorimetry?
DSC devices are built according to two basic measuring principles: the heat-flux principle and the power-compensated DSC principle. With the Heat-Flux DSC, the changes in the heat flow are calculated by integrating the ΔTref curve.

The DSCMoreThe melting of ice to water can easily be measured by differential scanning calorimetry. The DSC measurement curve shows a peak whose area corresponds to the enthalpy.
What is the difference between differential thermal analysis and Differential Scanning Calorimetry?
Differential thermal analysis (DTA) is suited for the determination of characteristic temperatures, while differential scanning calorimetry (DSC) additionally allows for the determination of caloric values such as the heat of fusion or heat of crystallisation.
What is Differential Scanning Calorimetry PDF?
A Differential Scanning Calorimetry, or DSC, is a thermal. analysis technique that looks at how a material's heat capacity (Cp) is changed by temperature. A sample of known mass is heated or cooled and the changes in its heat capacity are tracked as changes in the heat flow.
What is DSC in plastic testing?
Differential scanning calorimetry analysis, or DSC, is often used in the physical testing of polymers and plastics. This thermal analysis technique is typically used for process development, product research & development, and quality control applications.
What do you understand by DSC?
Differential Scanning Calorimetry (DSC) is a thermal analysis technique in which the heat flow into or out of a sample is measured as a function of temperature or time, while the sample is exposed to a controlled temperature program.
