China TGA 201 Thermogravimetric Analyzer - Reliable Suppliers & Factory for Material Analysis
🔬
Working Principle
Thermogravimetric analysis (TG, TGA) is a method of observing the changes in the mass of a sample with temperature or time during heating, constant temperature, or cooling processes, with the aim of studying the thermal stability and composition of materials.
The TGA103A thermogravimetric analyzer is widely used in research and development, process optimization, and quality monitoring in various fields such as plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metal materials, and composite materials.
