Advantages of using TGA for materials analysis:

Thermogravimetric analysis (TGA) uses heat to force reactions and physical changes in materials. TGA provides quantitative measurement of mass change in materials associated with transition and thermal degradation. TGA records change in mass from dehydration, decomposition, and oxidation of a sample with time and temperature. Characteristic thermogravimetric curves are given for specific materials and chemical compounds due to unique sequence from physicochemical reactions occuring over specific temperature ranges and heating rates. These unique characteristics are related to the molecular structure of the sample. When used in combination with FTIR, TGA/FTIR is capable of detailed FTIR analysis of evolved gases produced from the TGA.
