Micropore Analysis by Gas Adsorption Pore Size Distribution and Pore Volume and Area: Pores < 2nm diameter. Fully understanding micropore character is fundamentally important to a wide range of materials and applications, just a few examples are: catalysts, battery materials, hydrogen storage, carbons, zeolites and MOFs. More information can be found on our applications pages. At MCA Services we offer a range of dedicated micropore analysis options using the latest Micromeritics 3Flex micropore instrument. Crucially, micropore analysis provides a full set of pore size distribution data as well as pore volume and pore area data for pores smaller than 2nm diameter. These are obtained from specialised data reduction models such as DFT (Density Functional Theory) and Horvath-Kawazoe, although older statistical models can also be applied. This full characterisation of micropores provides considerably more information than the alternative statistical approaches.   Key Information: Micropore size distribution Micropore volume measurement Micropore area measurement Micropore only or full isotherm analysis DFT (Density Functional Theory) data reduction Flexible and comprehensive reporting options Additional mesopore & macropore characterisation Additional BET surface area measurement Nitrogen and Argon adsorption available Hydrogen adsorption / pressure composition plots Carbon dioxide adsorption at varying temperatures Other adsorbates available on request Comprehensive degassing options available With nitrogen and argon adsorption, analysis of the isotherm can be confined to the micropore range of pressures or extended to measure the full adsorption / desorption isotherm to provide micropore and mesopore / macropore distribution data. The 3Flex is an extremely powerful instrument and combined with comprehensive reporting options a wealth of information can be obtained. With our decades of experience we can recommend and tailor analyses and reports to suit your particular materials and ensure that the most relevant and important information is obtained. We can supply reports specified by our clients or we can assist in the selection of the most appropriate reports and data reduction methods based on the material being analysed and its application. Besides DFT and Horvath – Kawazoe  options, we can also apply alternative, historical methods such as  de-Boer t-Plot, S Plot and Dubinin methods to provide reports which can be used in direct comparison with existing data. Should a full isotherm be measured, mesopore data (pore volume and pore area) is most commonly generated by the BJH (Barrett, Joyner, Halenda) technique. However, DFT (Density Functional Theory) may also be applied which has the benefit of generating pore area and pore volume data continuously throughout the micropore and mesopore range.
