thermo gravimetric analysis(tga)

under the process of temperature variation(up/down/ constant temperature), it is to measure the whole changing process of the weight with the variation of the temperature and time.

by thermo-gravimetric analysis, we can test the stability and oxidation stability of the materials in different situations, make analyses towards the materialization process of resolving, adsorption, desorption, oxidation, restoring(including the further study on apparent reaction kinetics by using the result of tg), make quantitative calculation of material content, and measure moisture, volatile component and the content of all kinds of additives and fillers.

this method can be widely applied to the development, process optimization and quality control of plastic, rubber, coating, medicine, catalyzer, inorganic material, metal material, composite, etc.
