Differential Scanning Calorimetry - Analyzing and Testing

DSC- Differential Scanning Calorimetry

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)

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
Melting, crystallization, transformation and reaction heats (enthalpies)
Powders such as pharmaceuticals or minerals

Fibers, textiles
Viscous samples such as pastes, creams or gels
Liquids

We offer various DSC models, covering a broad temperature range from -180°C to 1750°C:

The DSC 404 F1 Pegasus and DSC 404 F3 Pegasus are two versions for the precise determination of specific heat and caloric effects, particularly in the high-temperature range.
The DSC 204 F1 Phoenix is our premium device for the temperature range from -180°C to 700°C. It unites excellent performance and highest flexibility. Coupled to a UV add-on (Photo-DSC 204 F1 Phoenix), it allows for monitoring the light-induced curing of, for example, paints, adhesives and resins.

With the DSC 204 HP Phoenix , measurements under increased pressure can be carried out (up to max. 150 bar).
The DSC 214 Polyma is a completely new concept. Designed especially for the characterization of polymer materials, its integral approach consists not only of the DSC instrument alone, but also incorporates the entire analytical process chain from sample preparation to evaluation.

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.

All differential scanning calorimeters discussed here operate based on the respective instrument standards as well as application or material testing specifications, including ISO 113587, ASTM E968, ASTM E793, ASTM D3895, ASTM D3417, ASTM D3418, DIN 51004, DIN 51007 and DIN 53765.

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.
