Differential Scanning Calorimetry (DSC)

The 6NAPSE Group uses Differential Scanning Calorimetry (DSC) to conduct thermal analysis of materials. The laboratory thus studies thermal transitions in order to know the behavior of materials and their nature.

Study the thermal transitions of a material

The 6NAPSE Group provides qualitative and quantitative information on the thermal transitions (melting, glass transition, crystallization, etc.) of a material thanks to the differences in heat exchange measured between the sample to be analyzed and a reference.

DSC (differential scanning calorimetry) is a thermal analysis technique. It measures the differences in heat exchange between a sample to be analyzed and a control (a reference).

The measurement consists of determining the variation in heat flux emitted or received by a sample when it is subjected to temperature programming, under a controlled atmosphere. During heating or cooling, any transformation occurring in a material is accompanied by an exchange of heat: DSC makes it possible to determine the temperature of this transformation and to quantify the heat. These measurements provide qualitative and quantitative information on the physical and chemical transformations leading to endothermic or exothermic heat exchanges.

The calorimetric analyzes by DSC in the laboratory are carried out under scavenging of an inert gas (argon or nitrogen) to avoid any potential reaction of the material with the atmosphere of the DSC oven. Oxygen stabilization also allows the study of the oxidation of an organic product.
