Micromeritics ASAP 2050 Xtended Pressure Sorption Analyzer

The fuel cell and its chemical energy source, hydrogen, have received much recent attention as a promising long-term solution to the world’s energy needs. Developing storage technologies involving advanced materials and the conversion of hydrogen to useful forms of energy are of critical importance. A fundamental understanding of hydrogen physisorption/chemisorption processes and adsorption/desorption kinetics is needed to optimise hydrogen uptake and release capacity rates. Knowledge of chemical reactivity and material properties, particularly with respect to exposure under different conditions (air, moisture, etc), needs to be gathered.

The Micromeritics ASAP 2050 Xtended Pressure Sorption Analyzer is designed to address these and many other elevated-pressure sorption needs. The instrument combines many of the capabilities of the ASAP 2020 with additional features that allow the user to obtain data in an extended-pressure environment.

The performance of the metal hydride is characterised by its hydrogen storage capacity (adsorption) and subsequent release (desorption) of hydrogen. The adsorption capacity of alkaline-exchanged zeolites is a key parameter for the design and optimisation of pressure swing adsorption processes. The active surface area and porous structure of catalysts have a great influence on production rates. The ASAP 2050 is also useful in generating surface area and porosity data for materials such as nanotubes, activated carbons and ceramics.
