TGA data can be used in kinetic studies of reactive chemicals, to predict product performance and chemical degradation characteristics.
Thermogravimetric analysis (TGA) instrument measures the amount and rate of change in the mass of a sample as a function of temperature and time in a controlled atmosphere. The technique is used to characterize materials that exhibit either mass loss or gain due to loss of volatiles, decomposition, and oxidation.
The TGA instrument is used primarily to determine the thermal and / or oxidative stabilities of materials as well as their compositional properties. TGA measurements provide valuable information that can be used for selecting materials, identifying reactivity, quantifying composition and / or impurity levels, polymer characterization, moisture, and volatile contents.

ASTM E2550, Standard Test Method for Thermal Stability by Thermogravimetry. This test method covers the assessment of material thermal stability through the determination of the temperature at which the material starts to decompose or reacts and the extent of mass change using thermogravimetry.
Typical specimen of 10 mg is required for a test.
Particle size of a solid sample should be considered, since bigger particles may show transition broadening due to the thermal conductivity lag into the specimen cores. Call us at 1-844-ioKinetic to discuss any specific sample preparation needs.
