Differential Thermal Gas Analysis (DTGA) is a high-sensitivity measuring method of gas evolution from, and gas absorption by a solid sample in a reactor gas stream, with arbitrary mixing ratio of active gas and inert gas by programmed temperature changes.
DTGA is expected to be of very wide application as much as differential thermal analysis, thermogravimetry and high temperature X-ray diffractometry in crystallography, physical chemistry, inorganic chemistry, organic chemistry and metallurgy.
The typical applications of DTGA are given, e. g. phase transition of SrMnO
3-x with absorption and evolution of oxygen.
