AccuSorp HP, a Micromeritics Technology, is a static high-pressure gas adsorption (physisorption) analyser designed to deliver unmatched precision at high pressures up to 200 bar, with automation features that streamline workflows across both research and industrial QC labs.

Built on more than 60 years of Micromeritics expertise in gas adsorption instrumentation, the AccuSorp HP provides publication-quality data, automated operation, and high sample throughput. Whether developing next-generation porous materials or performing routine production QC, the system delivers the precision and efficiency required for today’s modern laboratories.

The AccuSorp HP is ideally suited to applications including carbon capture, utilisation and storage (CCUS), hydrogen and natural gas storage, gas separation, catalyst development, and advanced porous materials research.

Unlike conventional low-pressure adsorption measurements, the AccuSorp HP characterises materials under the elevated pressures, encountered in real-world gas storage and separation applications. This enables users to accurately evaluate gas storage capacity, saturation behaviour, and adsorption kinetics, providing the data needed to predict material performance in practical operating environments and whether a material is viable at scale.

Designed for productivity as well as performance, the AccuSorp HP features dual analysis stations for parallel sample measurements, an intuitive touchscreen interface, and fully automated test methods. The result is a high-throughput, easy-to-use platform that delivers reliable high-pressure adsorption data while reducing operator workload and maximising laboratory efficiency.
