Introduction to the instrument

Differential scanning caloretry method (heat flow type DSC), as a classical thermal analysis method of thermal effect under controlled program temperature, has been widely used in various research and development, process optimization, quality control and failure analysis in the field of materials and chemistry. Using the DSC method, we are able to study the phase transition of inorganic materials, the melting of polymer materials, the crystallization process, the polycrystalline type phenomenon of drugs, the solid / liquid phase ratio of food such as oil, etc.

Instrument use

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