Differential Scanning Calorimetry (DSC)
You may delete a document from your Alert Profile at any time. Designed especially for the characterization of polymer materials, its integral approach consists not only of the DSC instrument alone, asmt also incorporates the entire analytical process chain from sample preparation to evaluation. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
If zstm document is revised or amended, you will be notified by email. 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, D33417 — oxidative-induction time and oxidation onset temperature, respectively Degree of curing in resins, adhesives, etc.

It unites excellent performance and highest flexibility. Proceed to Checkout Continue Shopping.
Note 4- To date, there is no similar or equivalent approved ISO standard. 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.
Subscription pricing is determined by: 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. The sample compartment is where an encapsulated sample of about 10 to 15 milligrams is placed for testing.
Please first log in with a verified email before subscribing to alerts. Using a DSC differential scanning calorimeter the following are commonly determined: A sample weight of 10 to 15 mg is required. Compact solids granulates, components, molds, etc. The DSC Polyma is a completely new concept. 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?
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: Note 1-True heats of fusion can only be determined in conjunction with structure investigation and frequently specialized crystallization techniques are needed. The reference compartment contains an empty aluminum pan d317 cover equivalent to those used to encapsulate a test sample.
D4317 to Alert PDF. Due to its versatility d3471 the high significance of its analytical output, e3417 scanning calorimetry DSC is the most often employed method for thermal analysis. Play Differential Scanning Calorimeter Video. As the voice of the U.

This test method covers the determination of heat of fusion and heat of crystallization of polymers by differential scanning calorimetry.
Of course, our Differential Scanning Calorimeters DSC meet the respective instrument and application standards, including: 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. Please first verify your email before subscribing to alerts.
Standards can be obtained from appropriate standards authorities. This standard is not included in any packages. Already Subscribed to this document. Further application areas include determining the effect of light on the shelf life of foods or technical oils, fats and lubricants. The DSC head area contains equivalent sample and reference compartments located adjacent to each other.
Note 2-This test method may not be applicable to all types of polymers as written see 6.
