Thermogravimetric Analysis (TGA) is a thermal analysis technique used to measure changes in a material’s weight as it is heated, cooled, or held at a constant temperature. The sample is placed on a highly sensitive balance inside a controlled furnace, and its mass is continuously recorded as the temperature changes. TGA helps identify processes such as moisture loss, decomposition, oxidation, or thermal stability, and can also provide information about a material’s composition and purity. It is widely used in polymers, pharmaceuticals, food, chemicals, and materials research to study stability, additives, and filler content. Because it provides direct insight into how materials behave under different thermal conditions, TGA is an essential tool for both research and industrial quality control.
