Thermal analysis instrument as a kind of analytical instrument, in the analysis process, the most important is the method, so do you have contact with overheating analysis instrument in daily life? What are the analytical methods of thermal analysis instruments?
Thermal analysis is an analytical method to study the relationship between temperature or heat and other physical and chemical properties. According to the measured physical quantities, it can measure the relationship between the physical properties such as mass, size, force, heat, sound, light, electricity, magnetism and heat or temperature.
Differential Scanning Calorimeters (DSC) can be divided into power compensation type and heat flow type. Power compensation DSC can be used to quantify heat, and the heat release or heat absorption can be obtained from the peak area of the measurement curve.
TG thermogravimetry analysis (TG thermogravimetry analyzers) can be used to test the change of sample quality during heating process, and analyze the temperature point of material property change, and the endothermic or exothermic heat in the change of physical property through the mass change curve, so as to study the thermal characteristics of the sample.
Differential thermal analysis (DTA) is a widely used thermal analysis technology. Put the tested sample and the reference sample in the same environment at the same time, and test the temperature change of the tested sample. Record the temperature difference between the test sample and the reference sample and draw the temperature difference curve to analyze the thermal performance of the tested sample.
In addition to the above three common thermal analysis methods, there are thermal mechanical measurement method, thermal expansion measurement method and so on. These thermal analysis methods have been widely used in the research and production of metals, ceramics, composite materials, coating materials, refractory materials, polymer materials and so on.
