Study Notes
Thermogravimetric Analysis (TGA)
- The primary purpose of TGA is to measure the change in mass of a sample as a function of temperature and time.
Understanding Sample Behavior
- TGA helps us understand the thermal stability, decomposition, and reaction kinetics of a sample.
- It provides information on the composition and properties of a material, such as moisture content, volatile content, and thermal degradation.
Changes in Materials with Temperature Increase
- As the temperature increases during TGA, certain materials may undergo physical or chemical transformations, such as melting, sublimation, or decomposition.
- These changes can lead to changes in mass, including weight loss or gain.
Importance of TGA
- TGA is considered a useful technique for understanding the behavior of different substances due to its ability to provide detailed information on thermal properties.
- It helps in the development of new materials, optimization of processing conditions, and quality control of products.
