Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis. TGA can measure the mass of a sample while temperature changes over time. Mass, temperature, and time are considered base measurements but many additional measures may also be derived from these three base measurements.
This measurement provides information about:
Physical Phenomena
- Phase Transitions
- Absorption
- Desorption
Chemical Phenomena
- Chemisorptions
- Thermal Decomposition
- Solid-gas Reactions (e.g., oxidation or reduction).
