Instrument Description:

Differential Scanning Calorimetry (Heat Flow DSC), as a classical thermal analysis method of thermal effects at controlled programmed temperatures, has long been widely used in today's research and development, process optimization, quality control and failure analysis of all kinds of materials and chemical fields. Using DSC method, we can study the phase transition of inorganic materials, melting and crystallization process of polymer materials, polycrystalline phenomenon of drugs, solid/liquid phase ratio of fats and oils and other foodstuffs. It is used to measure physical and chemical changes related to heat, such as glass transition temperature, melting point, melting temperature, crystallization and heat of crystallization, phase transition reaction heat, thermal stability of products, curing/cross-linking, and oxidation induction period.
