Simply put: to automatically measure accurate gas adsorption isotherms at process relevant conditions. Fundamentally understanding the gas storage capacity of a material is critical for researchers focused on carbon capture, gas separations, and gas storage applications.
The higher the pressure, the more adsorption occurs. This is because the increased pressure forces the adsorbate molecules closer to the adsorbent surface, making them more likely to stick. Additionally, the higher the concentration of the adsorbate, the more adsorption occurs. AccuSorp HP operates at pressures up to 200 bar, capturing the full adsorption behavior of materials at the conditions where they will actually be deployed.
The volumetric method is the established standard for high-pressure gas adsorption. For professionals prioritizing precise measurements and operational ease, volumetric adsorption systems facilitate straightforward calibration, minimal downtime, and seamless integration into existing workflows. Compared to gravimetric analysis, volumetric systems are more cost-effective to purchase and operate, and they don’t rely on a sensitive microbalance that can be damaged through routine use or require frequent recalibration.
Empower your laboratory to elevate its research quality and make data-backed decisions that drive innovation with every high-pressure adsorption experiment completed.
At low pressures, excess and absolute isotherms are nearly identical, but at high pressures, the difference becomes significant. An excess isotherm measures only the gas adsorbed above what would be present in the bulk gas phase, while an absolute isotherm accounts for the total amount of gas in the adsorbed layer, including the contribution of the bulk gas density.
For applications such as hydrogen storage and CO₂ capture, the absolute isotherm gives a more physically meaningful representation of true storage capacity.
Most real-world gas storage and separation processes operate at elevated pressures. including hydrogen storage tanks, CO₂ capture systems, and gas separation membranes. Measuring adsorption only at low pressure tells you how a material behaves in the lab, not how it will perform in deployment.
High-pressure adsorption data reveals the storage capacity, saturation behavior, and kinetics that determine whether a material is viable at scale.
AccuSorp HP is suited to a wide range of porous and particulate materials, including metal-organic frameworks (MOFs), covalent organic frameworks (COFs), activated carbons, shales and minerals, catalysts, and other advanced sorbents. Its high-pressure capability makes it particularly valuable for screening and evaluating materials intended for use in gas storage, carbon capture, and separation applications, where performance at elevated pressures determines real-world viability.
AccuSorp HP is compatible with a broad range of gases, including CO₂, H₂, CH₄, N₂, O₂, and NH₃ (ammonia), among others.
Compatibility with O₂ and NH₃ extends AccuSorp HP’s application range beyond many competing systems.
