TGA process utilizes stoichiometry and heat ratios to determine percentage of mass of a solute. Test and analysis is achieved by increasing the temperature of a sample gradually whilst plotting weight against temperature. TGA analysis is employed in research and testing to characterize materials such as polymers, to determine degradation temperatures, absorbed moisture content of materials, the level of inorganic and organic components in materials, decomposition points of explosives, and solvent residues.

The Thermogravimetric Analyzer (TGA) is an essential laboratory tool used for material characterization. TGA is used as a technique to characterize materials used in various environmental, food, pharmaceutical and petrochemical applications.
