Differential Scanning Calorimetry Testing

The DSC instrument is used primarily to determine glass transition temperatures, melting and boiling points, heat of fusion, specific heat, heats of reaction, and onset temperatures of reactions.

Differential scanning calorimetry is a technique to measure changes in material heat as a function of time and temperature. These heat changes are often associated with reactions or transitions in materials.

The measurements from the DSC instrument provide quantitative and qualitative information about physical and chemical changes that involve exothermic or endothermic processes, or changes in heat capacity.

DSC measurements provide valuable information that can be used for selecting materials, quantifying composition and / or impurity levels, polymer characterization, rate and degree of cure, crystallization time and temperature, oxidative and thermal stability, and reaction kinetics. This data can be used directly in process optimization and in kinetic studies of reactive chemicals, to predict product performance and chemical degradation characteristics.

Instrument

DSC 200 F3 Maia
DSC 200 F3 Maia Differential Scanning Calorimeter manufactured by Netzsch™ Group of Selb, Germany

Applicable Standard

ASTM E 537, Standard Test Method for the Thermal Stability of Chemicals by Differential Scanning Calorimetry. This test method covers the ascertainment of the presence of enthalpic changes in a test specimen using minimum quantities of material, approximates the temperature at which these enthalpic changes occur and determines their enthlpies (heat) using differential scanning calorimetry.
