Thermogravimetric analysis (TGA) is a thermal analysis method used to find phase transitions, analyze degradation reactions, and evaluate polymer properties. Element’s TGA testing services provide valuable insight into material behavior and characteristics.
How does thermogravimetric analysis work?
Thermogravimetric analysis is performed by heating a small sample to a predetermined temperature. The weight of the sample is constantly measured during the heating process, and changes in mass are recorded. Once the analysis is complete, our experts will review the resulting graph and note significant changes, including important transition points and deformations. From these results, we can draw conclusions about the material’s core properties.
Our TGA/DSC is used for testing in many applications at temperatures up to 1100⁰C over a wide range of heating rates. This technique is particularly useful for the following types of measurements:
- Compositional analysis of multi-component materials or blends
- Thermal stabilities
- Effects of reactive atmospheres on materials
- Moisture and volatiles content
- Collection of thermodynamic mass loss information
- Identification of hidden transitions obscured by mass loss

Thermomechanical Analysis (TMA)
TMA provides data on thermal properties by contacting the specimen with a quartz probe to measure CTE and Tg.
Differential Scanning Calorimetry (DSC)
DSC is a reliable and cost-effective method for measuring Tg, phase transitions, degree of cure, degree of crystallinity, and more.
Thermogravimetric Analysis (TGA)
TGA measures a material's thermophysical and thermochemical properties by measuring the change in specimen mass as a function of temperature and time.
