ABSTRACT
Thermogravimetric analysis (TG) is the study of weight changes of a specimen as a function of temperature. The technique is useful strictly for transformations involving the absorption or evolution of gases from a specimen consisting of a condensed phase. Most TG devices are configured for vacuum and/or variable atmospheres. The balances associated with TG's are highly sensitive, with resolutions down to lpg. These instruments may be used for a wide variety of investigations, from the decomposition of clays to high temperature oxygen uptake in the processing of superconducting materials.
