Differential Scanning Calorimetry

Differential scanning calorimetry or 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. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. Generally, the temperature program for a DSC analysis is designed such that the sample holder temperature increases linearly as a function of time. The reference sample should have a well-defined heat capacity over the range of temperatures to be scanned.

Due to its versatility and the high significance of its analytical output, differential scanning calorimetry (DSC) is the most often employed method for thermal analysis.

 

It can be used to investigate a great variety of materials:
Compact solids (granulates, components, molds, etc.) such as plastics, rubbers, resins or other organic materials, ceramics, glass, composites, metals and building materials
Powders such as pharmaceuticals or minerals
Fibers, textiles
Viscous samples such as pastes, creams or gels
Liquids
Typical Information That Can Be Derived from DSC Measurements:
Characteristic temperatures (melting, crystallization, polymorphous transitions, reactions, glass transition)
Melting, crystallization, transformation and reaction heats (enthalpies)
Crystallinity of semi-crystalline substances
Decomposition, thermal stability
Oxidative stability (OIT, OOT – oxidative-induction time and oxidation onset temperature, respectively)
Degree of curing in resins, adhesives, etc.
Eutectic purity
Specific heat (cp)
Compatibility between components
Influence of aging
Distribution of the molecular weight (peak form for polymers)
Impact of additives, softeners or admixtures of re-granulates (for polymer materials)

All NETZSCH DSC instruments work in accordance with the heat-flux principle and feature high detection sensitivity and long service lives – ideal conditions for successful application in research and academia, material development and quality control.
