Introduction
The shape of the glass powder significantly changes due to changes in the viscosity of the material after glass transition temperatures. This change may also be referred to as softening point. Shape changes are not revealed on the DSC curve because they are not energy changes, but they are often used in measuring the shape changes in glass powders because they appear as baseline shifts indicated as apparent changes in specific heat capacity in DTA.
Here, the glass powder was measured using DTA8611, a vertical type DTA, and the shape change of the sample was compared with the change in the baseline of the DTA curve.

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.
