The DSC head area contains equivalent sample and reference compartments located adjacent to each other.

The resulting thermal scan is then analyzed. Your Alert Profile lists the documents that will be monitored. The sample is heated at a controlled rate and a plot of heat flow versus temperature is produced. A sample weight of 10 to 15 mg is required. Note 2-This test method may not be applicable to all types of polymers as written see 6. Sensors with high calorimetric sensitivity, short time constants and a condensation-free sample chamber in the calorimeter cell guarantee high detection sensitivity and stable, reproducible baselines over the entire life cycle of a calorimeter: Using a DSC differential scanning calorimeter the following are commonly determined: Subscription pricing is determined by: We use cookies to personalize content and ads, provide social media features and analyze traffic to our website.

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?

If the document is revised or amended, you will be notified by email. Aetm 4- To date, there d3471 no similar or equivalent approved ISO standard. Standards can be obtained from appropriate standards authorities. Numerous upgrade possibilities allow adaption of this cost-effective calorimeter system to sophisticated applications. The DSC Polyma is a completely new concept. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing 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. It is x3417 used to characterize materials for their thermal performance. 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. Designed especially for the characterization of polymer materials, its integral dd3417 consists not only of the DSC instrument alone, but also incorporates the entire analytical process chain from sample preparation to evaluation.
