Thermal gravimetric analysis
TGA is a type of testing performed on samples that determines changes in weight as a function of temperature. Such analysis relies on a high degree of precision in three measurements: weight, temperature, and temperature change. The weight loss curve may require transformation before results may be interpreted. A derivative of the weight loss curve can identify the point where weight loss is most apparent. Thermal gravimetric analysis heats a mixture to a temperature which will decomposes components into a gas. TGA is commonly employed in research and testing to determine characteristics of materials such as polymers, to determine degradation temperatures, absorbed moisture content of materials, the level of inorganic and organic components in materials, and solvent residues. Our group mainly uses to measure hydration of salts, absorbed moisture content of materials, and degradation of organic components.
