High-Pressure Simultaneous Thermal Analyzer STA HP|High-Temperature & High-Pressure TGA-DSC System
The STA HP High-Pressure Simultaneous Thermal Analyzer is a high-precision and high-resolution thermal analysis system designed for simultaneous TGA (mass change) and DSC (thermal effects) measurements under extreme temperature (-170 °C to 1800 °C) and high-pressure conditions (up to 150 bar). It is especially suitable for applications requiring harsh environments, such as gas adsorption, metal oxidation/reduction, catalyst characterization, and gasification studies.
Key Features
- High-temperature & high-pressure capability: Operating range from -170 °C to 1800 °C with pressures up to 150 bar, compatible with various reactive gases.
- High-resolution measurement: TGA resolution down to 0.1 µg and DSC resolution down to 0.3 µW, ideal for detecting subtle reaction behavior.
- Excellent long-term baseline stability: Stable heat-flux design ensures reliable results during long-duration experiments.
- Wide atmosphere compatibility: Precise control under inert, oxidizing, reducing, or vacuum conditions.
- Advanced gas mixing control: Optional pressure-controlled gas mixing system (MFC) allows precise adjustment of gas composition and pressure.
- In-situ gas analysis capability: Compatible with online FTIR, Raman, and ELIF gas analysis systems.
Application Areas
- Pyrolysis studies (polymers, biomass, coal)
- Gasification reactions and carbon material analysis
- CO₂ capture and storage material research
- Gas adsorption isotherm analysis (H₂, O₂, etc.)
- Metal oxidation and reduction behavior
- Catalyst reaction properties and thermal effects
- TPD / TPO / TPR analysis (-196 °C to 1800 °C)
- Density determination and gas storage behavior
- Corrosive gas measurements (with optional magnetic suspension balance)
