SIMULTANEOUS THERMAL ANALYZER
Measures weight changes and endothermic or exothermic reaction
Simultaneous thermal analysis (STA) is a technique for measuring thermogravimetry (TG) and differential thermal analysis at the same time (DTA).
In thermogravimetry, we may examine the reaction temperature and rate of weight change in reactions including dehydration, thermal breakdown, evaporation, and oxidation by measuring the sample’s change in weight. The endothermic or exothermic reaction temperatures such as transition, melting, crystallisation, dehydration, decomposition, oxidation, and glass transition temperature are measured using differential thermal analysis (DTA). It can also be used as a TG-DSC by converting the DTA to DSC and calibrating it using melting peaks of standard metals.
The TG-DTA from Rigaku uses a horizontal differential triple-coil balance to cancel out numerous disturbances that cause TG drift, resulting in extremely accurate weight change measurements. As a standard, the sample controlled TG (SCTG) method is included. The temperature is regulated by the rate of change in weight of the sample in this method, which has two modes: constant reaction control (CRC) and stepwise isothermal analysis (SIA).
Furthermore, the TG-DTA sample observation system may take measurements while simultaneously recording visual images of the sample with a CCD camera. We can see shape or colour changes in the sample linked with a response through these photos. These photos aid in the interpretation of TG-DTA data.
