Subscription pricing is determined by: 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. If the document is revised or amended, you will be notified by email.
It is also used to characterize materials for their thermal performance. Eutectic purity Specific heat c p 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 What is the Difference Between DSC and DTA? Note 1-True heats of fusion can only be determined in conjunction with structure investigation and frequently specialized crystallization techniques are needed.
Compact solids granulates, components, molds, etc. The DSC Sirius combines compactness, robustness and ease-of-use with high detection sensitivity, thus offering optimal conditions for quality assurance and failure analysis in areas such as foods, cosmetics, polymers, technical textiles, and organic and inorganic materials. 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.

Please first verify your email before subscribing to alerts. This test method covers the determination of heat of fusion and heat of v3417 of polymers by differential scanning calorimetry.
The resulting thermal scan is then analyzed. The sample compartment is where an encapsulated sample of about 10 to 15 milligrams is placed for testing. Already Subscribed to this document. This standard is not included in any packages. Due to copyright restrictions, we are not able to provide copies of standards. 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.
Designed especially for the characterization of polymer materials, its integral approach astk not only of the DSC instrument alone, but also incorporates the entire analytical process chain from sample preparation to evaluation. We have no amendments or corrections for this standard. The reference compartment contains an empty aluminum pan and cover equivalent to those used to encapsulate a test sample.
