Thermomechanical analysis or TMA is a technique in thermal analysis in which a material’s change in dimension is monitored as function of temperature or time. In TMA, the material’s change in length revealed as expansion or shrinkage can be detected using different modes depending on the sample shape and measurement objective. The differential mode is recommended for materials with minute CTE (coefficient of thermal expansion) values where the reference is a material with a known thermal expansion for software correction. On the contrary, non-differential mode (single rod) such as tensile loading attachment is suitable for materials where the CTE is 10,000x larger than the CTE of the detection rod and support pipe which are made of SiO₂. The TMA8311 corresponds to both differential and non-differential mode. Here, we report the application of tensile loading mode in TMA for the measurement of fibers of cotton, silk and polyester.

TG-DTA is a hyphenated technology generally referred to as simultaneous thermal analysis (STA).
Quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature.
TMA is the measurement of a change in dimension or mechanical property of the sample while it is subjected to a controlled temperature program.
The compact humidity generator (HUM-1) is connected to the TG-DTA for measurements under constant relative humidity water vapor atmosphere.
TMA/HUM measures change in dimension or mechanical property of a sample while subjected to a temperature regime under water vapor atmosphere with a constant relative humidity.
In TG-FTIR, gases evolved by volatilization or thermal decomposition are qualitatively analyzed, which allows you to track changes in the generated amount along with the temperature change.
