Easy-to-use, robust, precise, optimized for everyday use – these are the features of the innovative DSC 214 Polyma. The unique design of this instrument encompasses everything needed for successful DSC investigations – regardless of whether the user is a beginner or an experienced professional. Above all, it is the unique software developments that are setting new standards: AutoEvaluation and Identify. These have the potential to revolutionize DSC analysis.
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|
|Viscous samples such as pastes, creams or gels|
|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.|
|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.
