    Differential Scanning Calorimetry (DSC)



    Definition

    DSC is used to study thermal transitions occurring in a material submitted to a temperature ramp (melting point, glass transition, crystallization…)

    Principle

    The DSC analysis consists in measuring the difference in heat flow between the sample and a reference (inert material) when both are submitted to the same temperature ramp. Any transformation occurring in the sample triggers off a heat flow, whereas the reference still be inert. The calorimeter measures the temperature and heat flow, that provides qualitative and quantitative information about physical and chemical transformations within the sample (exothermic or endothermic reactions).

    Examples of applications
