Thermogravimetric Analysis (TGA) measures the amount and rate of change in the weight of a material as a function of temperature or time in a controlled atmosphere. Measurements are used primarily to determine the composition of materials and to predict their thermal stability at temperatures up to 1000°C. The technique can characterize materials that exhibit weight loss or gain due to decomposition, oxidation, or dehydration. It is especially useful for studying polymeric materials, including composites, but also is widely applicable to other organic materials, such as lubricants and edible oils, and to a wide range of ceramics, metals and other inorganics.
What TGA can tell you
- Composition of multicomponent systems
- Thermal stability of materials
- Oxidative stability of materials
- Estimated lifetime of a product
- Decomposition kinetics of materials
- Moisture and volatiles content of materials
