Determining Storage Capacity and Heat of Adsorption for MOFs

In a continuing effort to expand its service offerings to serve more customer needs, Micromeritics Analytical Services (MAS) can now perform high-pressure sorption analysis using the Micromeritics ASAP 2050 Accelerated Surface Area and Porosity analyzer or the Particulate Systems HPVA II High Pressure Volumetric analyzer. Both instruments are ideally suited for determining the storage capacity and heat of adsorption for metal organic frameworks (MOFs), as well as other materials such as zeolites, carbons, and novel crystalline materials.

ASAP 2050 and HPVA II Analyzers

While retaining many design elements of Micromeritics’ popular ASAP 2020, the ASAP 2050 analysis manifold is equipped with a pressure transducer capable of operating from vacuum to 10 bars. This design allows the ASAP 2050 to collect high-resolution isotherms which may be used for determining the Heat of Adsorption. The Particulate Systems HPVA II operating pressure ranges from high vacuum to 200 bars. The span of the sample temperature during analysis can vary from cryogenic to 500 oC.

Applications

These instruments may be used with a large variety of gases including: methane, ethane, ethylene, propane, propylene, butane, carbon dioxide, carbon monoxide, nitrogen, oxygen, argon and nitrous oxide. The pressure capabilities vary between the two instruments, but both are particularly well suited for pressure swing adsorption ( PSA ) research applications.
