Thermogravimetric Analysis (TGA)
What is Thermogravimetry?
Thermogravimetric analysis is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about physical phenomena, such as Phase TransitionsThe term phase transition (or phase change) is most commonly used to describe transitions between the solid, liquid and gaseous states.phase transitions, absorption and desorption; as well as chemical phenomena including thermal Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition, and Solid-Gas ReactionsSolid-gas reactions are a type of heterogeneous solid-state reaction occurring when a reactive solid is exposed to a stream of reactive gas. Typical examples of solid-gas reactions are sorption and corrosion of metals.solid-gas reactions (e.g., OxidationOxidation can describe different processes in the context of thermal analysis.oxidation or reduction).
