TGA
|
Technical Concept |
|
Thermogravimetric Analysis or Thermal Gravim Analysis (TGA) is a method of thermal analysis in which changes in physical and chemical properties of materials are measured as a function of increasing temperature (with constant heating rate), or as a function of time (with constant temperature and/or constant mass loss). |
 |
|
TGA is commonly used to determine selected characteristics of materials that exhibit either mass loss or gain due to decomposition, oxidation, or loss of volatiles (such as moisture).
|
Application |
Common applications of TGA as listing may be useful for corroborating predicted material structures or simply used as a chemical analysis.
- Materials characterization through analysis of characteristic decomposition patterns
- Studies of degradation mechanisms and reaction kinetics
- Determination of organic content in a sample
- Determination of inorganic (e.g. ash) content in a sample
It is an especially useful technique for the study of polymeric materials, including thermoplastics, thermosets, elastomers, composites, plastic films, fibers, coatings, and paints. (wiki)
