Mercury Porosimetry Mesopore and Macropore Size, Volume & Area Measurement Mercury    porosimetry    provides    a    wealth    of    information    for understanding   the   porous   characteristics   of   any   material   with porosity   in   the   size   range   3.5   nm   to   650   µm.   The   technique   is applicable   to   virtually   any   solid   form,   from   powders,   through granules   to   single   solid   pieces,   films,   membranes,   fabrics   and coatings.   The   pore   volume,   pore   area   and   pore   size   present   in solid   materials   and   between   the   particles   of   powder   and   granules often    profoundly    affect    the    fabrication    and    performance    of materials.     Porosity     influences     the     efficiency,     efficacy     and functionality   of   materials   across   sectors   such   as   pharmaceuticals, catalysis,    energy    production    and    storage,    sorption    technology and    geology    &    environmental    science    and    construction.    It    is usually   necessary   to   consider   the   extent,   nature   and   effects   of porosity     at     all     stages     of     product     life-cycle,     from     the characterisation    of    raw    materials,    through    formulation    and fabrication   processes   to   final   use   and   application.   Knowledge   of the   full   porous   character   of   materials   is,   therefore,   critical   to   the understanding of materials and their application.

Key Applications Analysis of wide range of pore sizes 3.5nm to 650 µm Applicable to almost any solid sample form Dissolution rate of pharmaceutical tablets and granules Pharmaceutical powder blends and solid dose forms Assessment of powder inter-particulate size and volume Ceramic raw material and finished product characterisation Efficiency and efficacy of filter media Chemical activity of catalysts and electrocatalysts Fabrication of battery electrodes Battery separator and solid electrolytes selection Capacity and efficiency of battery electrodes and materials Production and performance of construction materials Production and performance of coatings and abrasives Characterisation of geological samples and fluid interactions Product life-cycle and capacity assessment Investigations of atypical performance and failures

Mercury    porosimetry    is    an    exceptionally    powerful    analytical technique   for   studying   materials   with   porosity   in   the   mesopore and   macropore   ranges.   At   MCA   Services   we   use   the   latest,   state- of-the-art    Micromeritics    AutoPore    V    instrument    to    offer    a comprehensive   list   of   flexible   analytical   and   reporting   options. Combined    with    our    decades    of    experience,    we    are    able    to recommend    and    tailor    analyses    to    your    materials    and    their performance   in   specific   applications.   We   are   also   happy   to   assist with   data   interpretation   so   that   you   receive   the   most   pertinent data   and   gain   the   maximum   insight   into   your   materials   and   their efficiency.   More   information   about   mercury   porosimetry,   its   use and background theory, is available on our YouTube channel.

Analytical Options and Highlights Pore volume (numerical and graphical reports) Pore Size Distribution (numerical and graphical reports) Pore Area (numerical and graphical reports) Average pore size by numerous calculations Additional calculation of bulk and skeletal density Additional calculation of absolute porosity (% volume) Characterisation of inter-particulate porosity Characterisation of intra-particulate porosity Permeability and Tortuosity measurement Mercury intrusion and intrusion / extrusion options Pore geometry assessment and cavity-to-throat size ratio Assessment of particle size via Mayer-Stowe method Extensive and flexible reporting options

For    materials    having    pores    smaller    than    3.5nm    our    gas adsorption     options     are     applicable.     Alternatively,     the     two techniques:   nitrogen   adsorption   and   mercury   porosimetry   can   be combined    to    provide    a    full    characterisation    of    micropores, mesopores    and    macropores.    In    addition    to    our    standard reporting   options   we   can   generate   alternative   representations, provide   graphical   overlay   plots   to   enable   direct   comparison   of multiple    samples    and    also    raw    data    for    further    inclusion    in reports and presentations.
