Description
Differential Scanning Calorimetry by AHP
Differential Scanning Calorimetry (DSC) investigates how the heat uptake or release of a sample material changes in comparison to a reference material when both are subjected to a controlled temperature change. This technique is very useful for determining Phase Transitions. The term phase transition (or phase change) is most commonly used to describe transitions between the solid, liquid, and gaseous states. Phase transitions such as melting and crystallization. Crystallization is the physical process of hardening during the formation and growth of crystals. During this process, the heat of crystallization is released.
Applications for Differential Scanning Calorimetry
Differential Scanning Calorimetry (DSC) is a vital technique across various industries, offering critical insights into the thermal properties of materials. Our advanced DSC solutions ensure precision and reliability for diverse applications:
Polymers and Plastics:
- Applications: Determining Glass Transition Temperature. The glass transition is one of the most important properties of amorphous and semi-crystalline materials, e.g., inorganic glasses, amorphous metals, polymers, pharmaceuticals and food ingredients, etc., and describes the temperature region where the mechanical properties of the materials change from hard and brittle to more soft, deformable or rubbery glass transition temperature, Melting Temperatures and Enthalpies. The enthalpy of fusion of a substance, also known as latent heat, is a measure of the energy input, typically heat, which is necessary to convert a substance from solid to liquid state. The melting point of a substance is the temperature at which it changes state from solid (crystalline) to liquid (isotropic melt). melting point, and Crystallization is the physical process of hardening during the formation and growth of crystals. During this process, heat of crystallization is released.
- Benefits: Ensures product consistency, optimizes processing, and aids new material development.
Composites and Advanced Materials:
- Applications: Assessing thermal behavior of composites and ceramics.

Food and Beverages:
- Applications: Analyzing melting behavior of fats and oils.
- Benefits: Improves texture, stability, and shelf life.
Chemicals:
- Applications: Studying reaction kinetics, Curing (Crosslinking Reactions). Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks. curing processes, and Thermal Stability. A material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer).
