TGA measures the weight change in materials as a function of time and temperature. The measurements provide basic information about the thermal stability of a chemical and its composition. TGA is one of the most commonly requested thermal techniques and it is used to characterize both inorganic and organic materials, including polymers. The measurement is typically carried out on milligram size samples with a heat rate of 10°C/min from 20° to 1000°C in a nitrogen atmosphere.

Specific measurements made by TGA include:

• Moisture and Volatiles Content
• Composition of Multicomponent Systems
• Thermal Stability
• Oxidative Stability
• Shelf-Life Studies Using Kinetic Analysis
• Decomposition Kinetics
• Effect of Reactive Atmospheres
