Differential scanning calorimetry (DSC) is a technique that measures the heat difference (DH dt) and temperature (t) between the input specimen and the reference object at a programmed temperature. Sample endothermic and exothermic as a function of temperature or time can be measured. It is used in a wide range of fields, such as: medicine, plastics, coatings, food, etc.
Applications:
It is mainly used to study the phase transition of polymers, determine melting temperature (melting point), melting enthalpy, crystallization temperature, crystallization enthalpy and oxidation induction period, glass transition, reaction temperature and enthalpy, and determine the specific heat and purity of the material, study the compatibility of each component in the mixture, calculate the crystallinity, reaction kinetic parameters, etc.
