STA

A Simultaneous Thermal Analyzer (STA) is an instrument capable of performing thermogravimetric (TG) and differential scanning calorimetric (DSC) measurements simultaneously. TG measures changes in the mass of a sample during heating or cooling, allowing analysis of reactions such as decomposition, oxidation, dehydration, and volatilization. DSC detects changes in thermal energy associated with endothermic and exothermic reactions or phase transitions (e.g., melting, glass transition), providing insight into the thermal properties of materials.

With STA (TG-DSC), both mass changes and thermal events can be obtained under identical conditions using a single sample. This improves measurement reproducibility and efficiency, enables the acquisition of correlated data with high precision, and enhances the reliability of the results.

STA is widely used in various fields such as materials development, chemistry, pharmaceuticals, batteries and energy, polymers, ceramics, metals, and organic and inorganic materials. It supports applications including compositional analysis, stability testing, and quality control.

Examples include thermal stability evaluation of new materials, decomposition temperature analysis of lithium-ion battery components, and thermal behavior analysis of catalysts, all of which contribute to ensuring product safety, improving performance, and optimizing manufacturing processes.
