Differential Scanning Calorimetry (DSC)
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. 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.
Combined with an FTIR analysisa DSC thermal scan can be used to help further identify certain types of materials by their melting points and is a useful tool for checking plastic parts or resins for contamination not seen by FTIR.

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. Due to copyright restrictions, we are not able to provide copies of standards.
The resulting thermal scan is then analyzed. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. A sample weight of 10 to 15 mg is required.

Using a DSC differential scanning calorimeter the following are commonly determined: It is also axtm to characterize materials for their thermal performance. As the voice adtm the U. It unites excellent performance and highest flexibility. Further application areas include determining the effect of light on the shelf life of foods or technical oils, fats and lubricants.
We have no amendments or corrections for this standard. The sample compartment is where an encapsulated sample of about 10 to 15 milligrams is placed for testing.
