Description
The RuboSORP MPA Series is a high-pressure volumetric adsorption analyzer designed to perform precision measurements of gas adsorption behaviour under elevated pressure and temperature conditions. It enables Pressure-Composition-Temperature (PCT) isotherm measurements, cycling kinetics, and high throughput screening, making it ideal for research into gas storage materials, advanced adsorbents and separation media.
Key Features
-
High-pressure capability: Performs volumetric sorption measurements up to approx. 200 bar (configurable) across a broad temperature range.
-
Multi-port / multi-station configuration: Supports one, two or three independent analysis ports, enabling parallel sample testing and enhanced throughput.
-
Precision volume and sensor control: Equipped with calibrated dosing volumes, multiple standard volume chambers (100 ml, 200 ml, 500 ml, 1000 ml) for refined kinetic acquisition, and high-accuracy pressure sensors (optional ranges include 0-10 bar, 0-50 bar, 0-100 bar, 0-200 bar) with resolution down to ~0.01 % FS.
-
Flexible temperature control: Standard ranges from ambient to ~500 °C; optional cooling to as low as –196 °C or dedicated low-temperature modules.
-
Fully-automated software interface: Enables programming of measurement sequences, real-time calculation of adsorbed gas quantity, automated isotherm curve fitting, and minimal user supervision.
-
High safety and reliability: Features include over-temperature and over-pressure protection, oven temperature stabilization (±0.1 °C), and robust sensor configurations.
-
Wide application scope: Suitable for hydrogen storage materials, methane/CO₂ adsorption in porous media, coal or shale gas studies, air-purification adsorbents, and cyclic sorption screening.

Applications
-
Measurement of high-pressure adsorption isotherms (PCT curves) for gas storage materials (e.g., hydrogen, methane).
-
Adsorbent screening for CO₂ capture, shale/coal-bed gas uptake and cycling performance under real-world pressures.
-
Kinetic studies and cyclic sorption testing under elevated pressure and temperature.
-
Calibration and characterization of adsorbent materials in energy, environmental and materials research labs.
Benefits & Why Choose It
-
Enables experiments under realistic high-pressure and temperature conditions, which many standard volumetric/gravimetric systems cannot handle.
-
Multi-port capability allows higher throughput and comparative testing across samples.
-
Precise sensor and volume configuration support accurate measurement of adsorption capacity and kinetics.
-
Fully automated operation reduces operator burden, increases reproducibility, and allows unattended testing.
Considerations
-
High-pressure instrumentation requires robust infrastructure: gas handling systems, safety interlocks, appropriate ventilation and compliance with pressure vessel standards.
-
Sample preparation and degassing protocols remain critical for accuracy; higher pressure adds complexity.
-
While the standard temperature range is ~ambient to ~500 °C, specialized low-temperature or ultra-high pressure options may require custom configuration and additional cost.
-
Ensure that your experimental requirements (pressure range, temperature range, number of ports, gas type) match the model configuration and options offered.
