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-100 High Pressure Volumetric analyzer. Both
instruments are ideally suited for determining t he storage capacity and heat
of adsorption for metal organic frameworks (MOFs), as well as other materials
such as zeolites, carbons, and novel crystalline materials.
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-100 operating pressure ranges from high vacuum
to 200 bars. The span of the sample temperature during analysis can vary from
cryogenic to 500 oC.
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.
Micromeritics Analytical Services is a contract laboratory specializing in
the physical characterization of fine particles. Analytical services conducted
in this cGMP laboratory environment include particle size distribution, B.E.T.
surface area, pore size distribution, pore volume distribution, density, water
vapor adsorption, active surface area, crystallite size, percent metal dispersion,
isosteric heat of adsorption, surface energy, mass spectrometry, microscopy,
method development, and much more.
