Explain the principle of TGA | Analytical Chemistry

Thermogravimetry is the technique in which change in the weight is recorded as the function of temperature Or time. The phenomenon is used for qualitative as well as quantitative analysis. Only solid substances can be analyzed by this method. In TGA following changes are possible: The second type of changes usually we do not perform in the laboratory. The first type of changes involves the loss in the mass or weight. This loss may be due to gas which is obtained by decomposition of reactants on heating or this loss may be due to H2O present with the reactants. This water is essential water. The essential water is water of crystallization or it is water of constituents. e.g. i) The loss due to gas is ii) The loss due to water of crystallization is iii) The loss of water due to the constituent is The graph is plotted mass Vs temperature or time. The graph thus obtained is known as Thermogram. Thermogram is a characteristic curve for a given compound. In this graph, the horizontal portion i.e. plateau indicate regions where there is no change in the weight while the curved portion indicates the loss in the mass. The heating temperature varies from Ambient to 1500°C.
