BAXIT High Temperature Differential scanning calorimeter
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 closed ceramic insulation furnace body structure greatly
improves signal sensitivity and resolution, and can obtain a more
stable baseline.
◆Equipped with an imported high-frequency core control processor,
the processing speed is faster and the control is more efficient.
◆The sensor is designed with imported materials and equipped with
K-type or E-type sensors that can be switched freely through
software. The sensor type can be flexibly selected for different
testing scenarios, especially suitable for phase transition and
vitrification experiments on polymer materials.
◆Independent atmosphere control can be achieved through software
intelligent settings, and the instrument can automatically switch
the gas path system, resulting in higher experimental efficiency.
◆The lower and upper computers of the equipment system have
multi-point temperature correction functions, which meet the needs
of different experimental scenarios and improve the accuracy of
temperature testing.
◆It has two experimental modes, FTC and STC, which can be set for
more friendly and flexible temperature control, meeting the needs
of different application scenarios and experiments. The temperature
control during the experimental process is more accurate, the
analysis of sensor signals is more efficient, and the experimental
effect is accurately controlled.
◆The fully temperature control 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 diversified, and the equipment has a
cyclic scanning function, with a maximum of 9999 cyclic scanning
times set and data automatically saved.
◆The sampling frequency of the sensor signal can be set between
1-10Hz, making the experimental method more flexible and the data
more controllable.
◆The design concept of dual temperature sensors allows for
simultaneous testing of both the internal temperature of the
furnace and the sample temperature.
◆The equipment system can conduct experiments on materials related
to heating, cooling, and isothermal processes.
◆The instrument adopts USB bidirectional communication, software
intelligent design, baseline deduction function, automatic drawing
of experimental process, and intelligent processing of various
data, such as glass transition temperature, oxidation induction
period, melting point and crystallization of substances, etc.
