Micropore Analysis by Gas Adsorption Pore Size Distribution and Pore Volume and Area: Pores < 2nm diameter. Micropores   are   those   smaller   than   2nm   diameter   and   present   in   a wide    range    of    materials,    for    example:    zeolites,    MOFs,    ZIFs    and activated   carbons   and   charcoals.   They   are   fundamentally   important   to the    functionality    and    performance    of    many    applications:    battery materials,   catalysts,   adsorbents,   sequestration   and   filter   materials   are just    a    few    examples.    Micropore    volume    and    area    typically    affect performance    capacity    and    micropore    size    affects    functionality    and efficiency.    A    certain    micropore    size    is    often    required    for    a    given application   to   be   efficient:   consequences   of   micropore   being   too   large or   small   are   a   loss   of   functionality   and   pore   clogging   /   blocking.   A   full understanding   of   micro-porous   character   in   terms   of   volume,   area   and size distribution is, therefore, required. At   MCA   Services   we   offer   a   range   of   micropore   analysis   options   using the    very    latest,    state-of-the-art,        Micromeritics    3Flex    instrument. Crucially,   dedicated   micropore   analysis   provides   a   full   set   of   pore   size distribution   data   as   well   as   pore   volume   and   pore   area   data.   These   are derived   from   specialised   data   reduction   methods   and   models,   such   as DFT   (Density   Functional   Theory),   NL-DFT   (Non-linear   Density   Functional Theory)    and    Horvath-Kawazoe.    These    provide    considerably    more information   (e.g.   pore   size   and   pore   size   distribution)   than   historical statistical    methods    such    as    t-plots,    alpha-S    plots    and    the    Dubinin models, al though these can also be applied if required. Key Information: • Micropore size values and micropore size distribution • Micropore volume measurement • Micropore area value and distribution • Choice of micropore only or full isotherm measurement • Micropore & mesopore characterisation from full isotherms • Data reduction by DFT (Density Functional Theory) • Data reduction by NL-DFT (Non-linear Density Functional Theory) • BET surface area included in reports • Choice of adsorptive: N2, Ar, CO2, H2, O2 or Xe • Other adsorbates available on request • Comprehensive degassing options • Hydrogen adsorption & pressure composition plots With    many    adsorptives,    analysis    can    be    confined    to    the    micropore region    or    extended    to    measure    the    full    adsorption    and    desorption isotherms.   This   extension   provides   micropore   and   mesopore   size,   area and   volume   distributions   in   a   single   analysis   and   set   of   reports.   The desorption    isotherm    can    provide    information    on    the    pore    shape present within the mesopore range. The    Micromeritics    3Flex    is    an    extremely    powerful    instrument    with cutting   edge   technology   and   software.   A   wealth   of   information   can   be gained   from   the   comprehensive   data   reduction   software   and   with   our decades   of   experience   we   are   always   happy   to   determine   the   best reporting   options   and   pore   models   for   every   sample.   The   combination of   expertise   and   instrumentation   ensures   that   you   always   receive   the most complete a nd appropriate data possible.
