High Pressure Visual Differential Scanning Calorimeter

Product Description

High-pressure visual DSC adopts a new unique design, which is capable of DSC data acquisition under high-pressure, high-temperature, and reactive gas conditions, and at the same time can monitor the real-time changes of the measured material at any time through the visual system. The high precision pressure control and accurate gas flow control provide users with better service in the process analysis of material component changes, process optimization, quality control and other fields.

Instrument Usage
It mainly measures physical and chemical changes related to heat, such as glass transition temperature, melting point, melting temperature, crystallization and heat of crystallization, heat of phase transition reaction, thermal stability of products, curing/crosslinking, and oxidation induction period.

Description of the reaction
The chemical reaction of the sample occurs in an isothermal temperature-controlled heating and high-pressure environment, with both the feedstock gas and pressurized auxiliary gas being fed in, as well as the thermal pressurization formed by the thermal expansion of the gases and the pressure relief and discharge of the generated gases.

Technical background
In conventional thermal analyzers due to the stepwise transmission of gases, which creates a pressure difference within the reaction line, it is difficult to maintain a constant pressure and flow in the reaction environment, especially when the water vapor generated at elevated temperatures after subzero frosting causes severe fluctuations in the DSC baseline of the sample.

prescription
Enabling the new microelectronic manipulation technology, mechanical defrost adjustable meter and high precision controllable pressure stabilization technology, we break through this world technical bottleneck and complete the dynamic balance of gas under stable pressure, i.e., the dynamic balance of pressure in the internal cavity of the reactor, and the addition of the defrost system ensures no DSC signal oscillation phenomenon and guarantees that there is no fluctuation in the DSC baseline.

Instrument Features
Micrographic function with PDSC at the same time.
Experiments under various atmospheres such as N2, Ar, He, etc. can be performed under high pressure.
The built-in pressure gauge shows the actual pressure in the test cell.
External pressure and flow controllers for precise pressure control in static and dynamic programmable atmospheres.
Optical observation of specimens heated or cooled in DSC allows simultaneous recording of specimen changes due to relaxation, melting or reaction processes.

Microscope systems
The high-pressure DSC with the equipped CCD electron microscope system synthesized system is able to make optical observation of the sample during heating or cooling in the DSC. This optical information allows a precise interpretation of the phenomena measured in the DSC curves.The CCD electron microscope system cleverly uses the principle of image refraction, which effectively solves the effect of temperature on the image.
