- TGA: ThermoGravimetric Analysis measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere to determine the thermal stability and composition.
- DTA: (Differential Thermal Analysis) and DSC (Differential Scanning Calorimetry) measure the thermal transitions in materials by monitoring temperatures and heat flows.
DTA is qualitative while DSC is quantitative. Glass transition temperatures, phase changes, heat capacity, cure kinetics and thermal degradation can be monitored by these techniques. Modulated DSC can be both faster and more accurate.
- DMTA: Dynamic Thermo-Mechanical Analysis measures the mechanical properties of materials under stress as a function of time, temperature, and frequency.
- DETA: Dynamic Electrical Thermal Analysis measures the electrical properties of materials as a function of time, temperature, and frequency.
- TMA: Thermo-Mechanical Analysis measures the change in dimensions or in a mechanical property of the sample while it is subjected to a temperature regime.
- Minimat is a miniature materials testing apparatus.
- STA: Simultaneous application of TGA and DSC to a single sample to yield more information than separate tests in different instruments.
