Application of thermogravimetric analyzer
Thermogravimetric analyzer, referred to as “TGA”, is a thermal analysis instrument that measures the relationship between the temperature and mass of a substance by thermogravimetric method. The main principle is to obtain the thermogravimetric curve of the material by setting the temperature of the sample to make it change, and then analyze the spectrum analysis by using analysis software to analyze the weightlessness at different stages, so as to study the characteristics of different materials. It is widely used in food, metal, pharmaceutical, chemical and polymer materials industries.
Application of thermogravimetric analyzer
What are the applications of thermogravimetric analyzer?
1, the application of polymer materials. The thermogravimetric analyzer is used to study the thermal stability of materials, the stability of additives, the quantitative analysis of copolymers and blends, the study of thermal cracking and thermal aging of polymers.
2. Application in the pharmaceutical industry. The thermogravimetric analyzer is used to make it undergo chemical reactions such as type transformation, melting and sublimation at a certain temperature. The melting point and boiling point of the drug are determined and the purity is tested to determine the characteristics and changes of the drug, so as to conduct research.
3. Application of environmental monitoring. Determine various changes in the environment, such as dehydration, decomposition, degradation of waste, etc. Combined with other techniques to determine the total amount of carbon and soluble and insoluble organic matter in suspended particles in the air.
4, the application of high temperature resistant materials. Such as special rubber, plastic and other materials, through the TGA constant temperature insulation setting, observing its weightlessness at a certain temperature can evaluate the high temperature resistance of the material, convenient and simple.
5, the application of organic and inorganic materials. The weight loss temperature of most organic materials is about 400-500℃, and the mass of organic components can be roughly obtained by the weight loss of this temperature segment in the TGA curve.
Application of thermogravimetric analyzer
What are the features of the thermogravimetric analyzer?
1, integrated model design, small and light, easy to handle.
2, open cover design, easy to test and place samples, will not contact its material with the furnace body.
3, the furnace body heating using noble metal nickel-chromium wire double row winding, reduce interference, more high temperature resistance.
4, the furnace body has high insulation, while using three layers of cover to seal, to avoid some special materials contact with the air.
5, imported chip, fast measurement speed, high accuracy.
6, multi-stage temperature setting, two-way operating system, improve experimental efficiency.
