BAXIT Differential scanning calorimeter(Liquid nitrogen refrigeration)

Instrument introduction:

Differential scanning calorimeter (heat flow DSC) is a classic thermal analysis method of thermal effects under controllable program temperature. It is used in the research and development, process optimization, quality control and failure analysis of various materials and chemistry fields. It has been widely used in various occasions. Using the DSC method, we can study the phase transition of inorganic materials, the melting of polymer materials, the crystallization process, the polymorphism of drugs, the solid/liquid ratio of foods such as oils and fats.

Instrument use:

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, solidification/crosslinking, oxidation induction period, etc. To

Main features:

◆The integrated design of the entire machine reduces signal loss and interference, greatly improves signal sensitivity and resolution, and can obtain a more stable baseline.

◆Equipped with an imported high-frequency core control processor, it has faster processing speed and more efficient control.

◆The use of imported high sensitivity sensors effectively improves the sensitivity and accuracy of DSC signals.

◆The mutually independent atmosphere control can be intelligently set through software, and the instrument automatically switches the air path system, resulting in higher experimental efficiency.

◆The lower and upper computers of the equipment system have multi-point temperature correction functions, meeting the needs of different experimental scenarios and improving the accuracy of temperature testing.

◆There are two experimental modes available, FTC and STC, which are more friendly and flexible in temperature control, and can meet the needs of different application scenarios and experiments. The temperature control during the experimental process is more precise, and the analysis of sensor signals is more efficient.

◆The fully controlled temperature system adopts an optimized dynamic PID algorithm, which greatly avoids the shortcomings of traditional PID algorithms and improves the robustness of dual mode temperature control.

◆The 12 step program temperature control setting makes the 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.

◆Independent dual temperature sensors can simultaneously test the furnace temperature and sample temperature separately.

◆The equipment system can conduct temperature rise, drop, and isothermal related material experiments.

◆The instrument adopts USB bidirectional communication, supports self recovery connection, software intelligent design, has baseline deduction function, automatic plotting of experimental process, and intelligent processing of various data, such as calculation of enthalpy, glass transition temperature, oxidation induction period, melting point and crystallization of substances, etc.
