Micromeritics HPVA II

HPVA II – High-Pressure Gas Adsorption and Desorption Analyzer

The Micromeritics HPVA II delivers precise, high-pressure gas adsorption and desorption isotherms for studying hydrogen, methane, CO₂, and other gases. Using the static volumetric method, it characterizes adsorption behavior from high vacuum up to 200 bar and from cryogenic to 500 °C, enabling accurate insights into gas storage, separation, and capture processes.

Designed for advanced research in hydrogen storage, carbon-capture and sequestration, fuel cells, and shale gas or hydrocarbon trapping, the HPVA II analyzes materials such as MOFs, zeolites, activated carbons, and porous composites using only a few milligrams of sample.

At Prisma Scientific, our application team provides method development, data interpretation, and training to ensure accurate and reproducible high-pressure measurements tailored to your research or industrial process.

Key Applications

• Hydrogen and natural-gas storage

• Carbon dioxide sequestration

• Catalysis and fuel-cell materials

• Shale gas and coal-bed methane studies

Why Choose HPVA II

With its dual free-space measurement, automated temperature control, and MicroActive™ interactive software, HPVA II delivers unmatched reproducibility and resolution across a broad operating range. Four integrated temperature-control options — from cryostats (30 K) to furnaces (500 °C) — enable flexible experimental design. Pneumatic stainless-steel manifolds, precision servo valves, and leak-safety sensors guarantee reliable, safe, and long-term operation even under extreme conditions.
