elemental analyzer / temperature / benchtop / thermomechanical

TMA is the measurement of a change of a dimension or a mechanical property of the sample while it is subjected to a temperature regime.

TMA uses interchangeable probes at varied loads to make a number of measurements, including the softening temperature or glass transition temperature, tensile modulus, compression modulus, the thermal expansion, melting temperature, crystalline phase transition temperature, crystalline to amorphous transition temperatures, and creep under load, by measuring the change of a dimension of a material.

TMA includes several variations according to the attachment probe and the methods of the attachment probe are applied: compression loading, tensile loading, penetration, 3-point bending methods.

Rigaku adopts differential expansion principle where the thermal expansion or shrinkage generated from the detection mechanism itself can be canceled. It offers high accuracy and excellent reproducibility in expansion and shrinkage measurements, even with low expansion materials or thin materials. It can also measure using the non-differential or conventional expansion method.
