In the case of evaluate material, it is preferable to evaluate at the measurement condition same as in the real environment. It is necessary to evaluate in humidity control atmosphere because not only for kinds of atmosphere gas, but also for the effect of humidity which can be not negligible when the material is used in real environment of high-temperature and humidity. It is available to perform the thermal analysis in controlled water-vapor atmosphere by using the humidity generator (HUM-1). In present work, we study the polyester of thermal decomposition in humidity atmosphere.
TG-DTA is a hyphenated technology generally referred to as simultaneous thermal analysis (STA).
DSC is a thermal analysis technique that quantifies the amount of energy in a reaction.
Quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature.
DSC8271 is a high-temperature type DSC with a maximum temperature of 1,500°C.
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.
Thermo Mass Photo combines simultaneous thermal analysis with mass spectrometry. This technique is suitable for the qualitative analysis of evolved gases coincident with the STA signal.
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.
