Description:
Differential Scanning Calorimetry (DSC), as a classic thermal analysis method for thermal effects under controllable program temperature, has been widely used in various fields of materials and chemistry, including research and development, process optimization, quality 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 polymorphic phenomenon of drugs, and the solid/liquid phase ratio of foods such as oils and fats.
Instrument usage:
Measure 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.
Main features:
1. The new fully enclosed metal furnace body design structure greatly improves sensitivity, resolution, and baseline stability.
2. Imported alloy sensors are used, which are more corrosion-resistant, anti-oxidation, and have high sensor sensitivity.
3. Adopting Cortex-M3 core ARM controller, it has faster processing speed and better temperature control.
4. Adopting USB bidirectional communication, fully realizing intelligent operation.
5. Adopt a 7-inch 24 bit full-color LCD touch screen to display the status and data of the instrument in real time.
6. Intelligent software design, instrument automatic drawing throughout the process, software can achieve various data processing, such as enthalpy calculation, glass transition temperature, oxidation induction period, melting point and crystallization of substances, etc.
