DSC-600L minus 150 fully automatic pressurized low-temperature differential scanning calorimeter
PIC-(DSC-600L minus 150 fully automatic pressurized low-temperature differential scanning calorimeter)
Instrument Introduction:
Differential scanning calorimetry (DSC), as a classic thermal analysis method for thermal effects under controllable program temperature, has been widely applied in various fields of materials and chemistry, such as research and development, process optimization, quality inspection and control, and failure analysis. By using DSC method, we can study the phase transition of inorganic materials, the melting and crystallization process of polymer materials, the polycrystalline phenomenon of drugs, and the solid/liquid phase ratio of foods such as oils and fats.
