The sample is heated at a controlled rate and a plot of heat flow versus temperature is produced. 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.
Note 2-This test method may not be applicable to all types of polymers as written see 6. Please first verify your email before subscribing to alerts. Designed especially for the characterization of polymer materials, its integral approach consists not only of the DSC instrument alone, but also incorporates the entire analytical process chain from sample preparation to evaluation.
Differential Scanning Calorimetry (DSC) – Argen Polymer LLC
It unites excellent performance and highest flexibility. 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. 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.
This standard is not included in any packages.
Note 4- To date, there is no similar or equivalent approved ISO standard. Due d34177 copyright restrictions, we are not able to wstm copies aetm standards. 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: 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.

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. Subscription pricing is determined by: Using a DSC differential scanning calorimeter the following are commonly determined: As the voice of the U. We have no document history for this standard.
Further application areas include determining the effect of light on the shelf life of foods or technical oils, fats and lubricants. Already Subscribed to this document. Proceed to Checkout Continue Shopping. Of course, our Differential Scanning Calorimeters DSC meet the respective instrument and application standards, including: The reference compartment contains an empty aluminum pan and cover equivalent to those used to encapsulate a test sample.
Numerous upgrade possibilities allow adaption of this cost-effective calorimeter system to sophisticated applications. Note 1-True heats of fusion can only be determined in conjunction with structure investigation and frequently specialized crystallization techniques are needed. The DSC Polyma is a completely new concept.
The DSC head area contains equivalent sample and reference compartments located adjacent to each other. This standard is also available to be included in Standards Subscriptions. The resulting thermal scan is then analyzed. By using this site you agree to the placement of cookies on your computer in accordance with the terms of our data protection policy.
