Differential Scanning Calorimetry
Differential scanning calorimetry (thermal flow DSC), as a classic thermal analysis method of thermal effects under controllable program temperature, is used in research and development, process optimization, quality control and failure analysis in various materials and chemical fields today. It has been widely used in various occasions. Using the DSC
method, we can study the phase transition of inorganic materials, the melting and crystallization processes of polymer materials, the polymorphism of drugs, the solid/liquid phase ratio of foods such as oils and fats, etc.
Usage:
Measure physical and chemical changes related to heat, such as glass transition temperature, melting point, melting temperature, crystallization and crystallization heat, phase transformation reaction heat, product thermal stability, solidification/cross-linking, oxidation induction period, etc.
Reference standard:
ISO 11357-2: 1999 Part 2: Determination of glass transition temperature;
ISO 11357-3: 1999 Part 3: Determination of melting and crystallization temperatures and enthalpy;
ISO 11357-3:1999 Part 6 Determination of oxidation induction period, oxidation induction time (isothermal OIT) and oxidation induction temperature (dynamic OIT).

Machine Features
The integrated design of the whole machine reduces signal loss and interference, greatly improves signal sensitivity and resolution, and can obtain a more stable baseline.
Equipped with imported high-frequency core control processor, the calculation processing speed is faster and the control is more efficient. Use imported high-sensitivity sensors to effectively improve the sensitivity and accuracy of DSC signals. Independent atmosphere control can be intelligently set through software, and the instrument automatically switches the gas circuit system, making the experiment more efficient. The lower computer and upper computer of the equipment system have multi-point temperature correction functions to meet the needs of different experimental situations and improve the accuracy of temperature testing.
It has two experimental modes, FTC and STC. The temperature control is more friendly and flexible, and can meet the needs of different experiments in different application scenarios. The temperature control of the experimental process is more precise, and the analysis of sensor signals is more efficient. The full temperature control system adopts an optimized dynamic PID algorithm, which greatly avoids the shortcomings of the traditional PID algorithm and improves the robustness of dual-mode temperature control.
12-level programmable temperature control settings make experimental methods more diverse. The sampling frequency of the sensor signal can be set from 1 to 10Hz,
making the experimental method more flexible and the data more controllable. Dual temperature sensors that are independent of each other can test the furnace body temperature and sample temperature separately at the same time. The equipment system can conduct heating, cooling and isothermal related material experiments.
The instrument uses USB two-way communication, supports self-restoring connection, and has intelligent software design, with a baseline deduction function, automatic drawing of the experimental process, and intelligent processing of various data, such as calculation of heat enthalpy, glass transition temperature, and oxidation induction period. , melting point and crystallization of substances, etc.
