Thermogravimetric analysis (TGA) is based on the measurement of the mass change of a sample under controlled ambient conditions as a function of temperature and time. Physical and chemical changes such as, for example, drying, sublimation and evaporation of the sample, as well as decomposition and pyrolysis can be detected and investigated under exclusion of oxygen. In addition, the reaction with the surrounding atmosphere, for example for the investigation of the oxidation stability, can also be measured by measurement technology. The results allow conclusions to be drawn about the specific thermal behavior and thermal stability of the sample as well as statements on volatile constituents.
