Overview
Huicheng DTA-1550 Differential Thermal Analyzer is an instrument that measures the temperature difference between a substance and a reference substance under a programmed temperature control. Differential Thermal Analysis Linear dispersion describes the temperature difference between the sample and the reference substance as a function of temperature or time. The temperature change is caused by the endothermic or exothermic effect of the phase transition or reaction. It is suitable for a variety of chemical reactions and physical transformation processes.
Features
1. The new fully enclosed ceramic insulation furnace body design structure has better temperature control effect and can continue to withstand high temperature.
2. Using Platinum Rhodium Alloy Sensor, more anti-corrosion, anti-oxidation, Sensor sensitivity is high.
3. With Cortex-M3 core ARM controller, the computing processing speed is faster and the temperature control is more accurate.
4. Adopt USB two-way communication for fully intelligent operation.
5. Adopt 7-inch 24bit color full-color LCD Touchscreen to display instrument status and data in real time.
6. Intelligent software design, automatic drawing of the instrument, the software can realize various data processing, such as enthalpy calculation, Glass transition temperature, oxidation induction period, material melting point and crystallization.
Principle
Differential thermal analysis measures the temperature difference and temperature relationship between a substance and a reference at a programmed temperature. Differential thermal analysis Linear dispersion shows that the temperature difference between the sample and the reference varies with temperature or time, and the temperature change is caused by the endothermic or exothermic effects of phase transitions or reactions, such as melting, crystallization, oxidation reduction, etc.
Applications
Phase transitions, melting, crystal structure transitions, boiling, sublimation, evaporation, dehydrogenation reactions, fracture or analysis reactions, oxidation or reduction reactions, lattice structure destruction, Miscellaneous chemical reactions
Steps
1. Connect the instrument power supply and working environment.
2. Connect the computer through the USB interface and install the supporting software.
3. Use Touchscreen to set temperature program parameters such as heating rate and thermostatic time.
4. Place the sample and reference and initiate the test procedure.
5. The instrument automatically controls the temperature and collects data to display the status in real time.
6. After the test is completed, use the software for data processing and analysis.
7. Optional one-click Adjustment for temperature correction.
Notice
Make sure the Power Supply is AC 220V 50Hz to avoid voltage mismatch.
• Check the furnace structure before operation to ensure that the upper open lid structure is normal.
• Pay attention to anti-corrosion and oxidation environment when using Platinum Rhodium Alloy Sensor.
• Set the heating rate within the range of 0.1 to 80 ° C/min to avoid exceeding the limit.
• Regularly use standards for temperature calibration to ensure data accuracy.
• Ensure that the Air-Cooled system works properly during programmed cooling.
• Baseline adjustment during software operation, optimizing results through slope and intercept.
