Thermal Analysis
Thermal analysis
Also found in: Acronyms, Encyclopedia.Thermal analysis is a branch of materials science where the properties of materials are studied as they change with temperature. Several methods are commonly used – these are distinguished from one another by the property which is measured:
- Dielectric thermal analysis): dielectric permittivity and loss factor
- Differential thermal analysis: temperature difference versus temperature or time
- Differential scanning calorimetry: heat flow changes versus temperature or time
- Dilatometry: volume changes with temperature change
- Dynamic mechanical analysis: measures storage modulus (stiffness) and loss modulus (damping) versus temperature, time and frequency
- Evolved gas analysis: analysis of gases evolved during heating of a material, usually decomposition products
- Laser flash analysis: thermal diffusivity and thermal conductivity
- Thermogravimetric analysis: mass change versus temperature or time
- Thermomechanical analysis: dimensional changes versus temperature or time
- Thermo-optical analysis: optical properties
- Derivatography: A complex method in thermal analysis

TMA7000 Series
The Hitachi TMA7000 Series Thermomechanical Analyzer has doubled its sensitivity compared with our conventional model. It measures a wide range of samples, including thin film and small samples, as it uses the total expansion method and does not limit sample shapes. Changing the modes between push, penetration, and tension is done by simply replacing the probe. A wide range of options, such as an automatic cooling unit, ensures the ease of use and highly accurate measurement.
