HSC-4 differential scanning calorimetry Introduction: Differential scanning calorimetry (DSC), as a classical thermal analysis method of thermal effect at controllable program temperature, has been widely used in various fields such as research and development, process optimization, quality control and failure analysis in the field of materials and chemistry. By using DSC method, we can study the phase transition of inorganic materials, melting and crystallization processes of polymer materials, polycrystalline phenomena of drugs, and the solid/liquid phase ratio of foods such as oils. Other uses Measure physical and chemical changes related to heat, such as glass transition temperature and melting point. Melting temperature, crystallization and crystallization heat, phase transition reaction heat, product thermal stability, curing/crosslinking, oxidation induction period, etc. Note: The thermal stability test during the oxidation induction period is applicable to the national standard GB/T17391-1998 characteristic: 1. The heat flow differential scanning calorimetry has good repeatability and high accuracy, especially suitable for accurate measurement of specific heat. 2. The independently developed gas chromatography and mass spectrometry connectors, constant temperature bands, and constant temperature controllers can fully ensure the secondary detection of tar and various reaction gases. 3. A comprehensive two-way atmosphere control system using a mass flow controller; During the measurement process, a two way intake method can be selected, and the software settings automatically switch. 4. The instrument is equipped with standard materials, and users can calibrate each temperature range to reduce instrument errors. Automatic drawing throughout the process, software can achieve various data processing, such as calculation of enthalpy, glass transition temperature, oxidation induction period, melting point and crystallization of substances, and so on. 5. Large screen LCD display, real-time display of instrument status and data, two sets of temperature measuring thermocouples, one set to display the sample temperature during operation, and the other set of thermocouples to display the furnace temperature in real time.
