Differential scanning calorimeter

First, introduction of the instrument:

Differential scanning calorimetry (DSC), as a classical thermal analysis method of thermal effect under controlled program temperature, has been widely used in today's research and development of various materials and chemical fields, process optimization, quality control and failure analysis. Using DSC method, we can study the phase transformation of inorganic materials, melting of polymer materials, crystallization process, polycrystalline phenomenon of drugs, the solid/liquid phase ratio of food such as fats and fats.

Second, instrument use:

Measurement of physical and chemical changes related to heat, such as glass transition temperature, melting point, melting temperature, crystallization and crystallization heat, phase transition reaction heat, product thermal stability, curing/crosslinking, oxidation induction period, etc.
