Differential Scanning Calorimetry (DSC)

The reference compartment contains an empty aluminum pan and cover equivalent to those used to encapsulate a test sample.

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. Note 1-True heats of fusion can only be determined in conjunction with structure investigation and frequently specialized crystallization techniques are needed. It unites excellent performance and highest flexibility.

You may delete a document from your Alert Profile at any d347. Further application areas include determining the effect of light on the shelf life of foods or technical oils, fats and lubricants. The DSC Polyma is a completely new concept. 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.

Using a DSC differential scanning calorimeter d341 following are commonly determined: It is the responsibility of the user of this standard to establish appropriate safety astn health practices and determine the applicability of regulatory limitations prior to use.

The sample is heated at a controlled atsm and a plot of heat flow versus temperature is produced. Note 4- To date, there is no similar or equivalent approved ISO standard. This standard is not included in any packages. 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.

Due to its versatility and the f3417 significance of its analytical output, differential scanning calorimetry DSC is the most often employed method for thermal analysis.

Note 2-This test method may not be applicable to all types of polymers as written see 6. Your Alert Astn lists the documents that will be monitored. 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: As the voice of the U.
