Porosimetry by Gas Adsorption Mesopore and Macropore Size, Volume & Area Measurement Micropores,   mesopores   and   small   macropores   are   conveniently   studied   by   gas   adsorption   and   MCA   Services have    a   comprehensive   range   of   options,   including   various   adsorptive   gases   for   the   generation   of   pore   size, volume   and   area   data.   Powerful   state-of-the-art   instrumentation   combined   with   our   decades   of   experience, means   that   we   are   can   recommend   and   tailor   analyses   to   suit   your   materials   and   their   function   as well   as   provide   input   to   data   interpretation   so   that   you   gain   the   most   information.   This   page   refers to    mesopore    and    macropore    analysis    using    our    Micromeritics    TriStar    II    Plus    instrument.    For dedicated micropore analysis please see our Micropore Analysis page. Key Information: Pore volume and pore area distributions by pore size Flexible analytical options tailored to specific samples Full gas adsorption & desorption isotherms Pores in the range 2nm to 350nm analysed by nitrogen adsorption BET Surface Area included in analyses Standard reporting format with tabulated and graphical data Flexible reporting options can be extended to specialised formats as required Nitrogen and argon adsorption available Micropore (pores < 2nm) analysis by carbon dioxide adsorption at 0 deg C Comprehensive options for data reduction and presentation Flexible and comprehensive degassing options Gas   adsorption   is   a   full   porosimetry   testing   method   for   pore   size   distribution,   pore   area   and   pore   volume data.   These   are   reported   as   standard   together   with   the   multipoint   BET   surface   area   of   the   sample.   Typically pore   sizes   in   the   range   2   nm   to   350   nm   diameter   are   measured   by   this   technique,   although   this   range   may be   extended   depending   on   the   nature   of   the   sample.   Nitrogen   adsorption   is,   therefore,   ideal   for   the   full characterisation   of   mesoporous   materials   and   can   be   tailored   to   additionally   provide   a   good   understanding of   the   presence   and   extent   of   microporosity   as   a   rapid   and   cost   effective   screening   technique   in   a   single analysis .   More   extensive   characterisation   of   microporosity   is   provided   through   our   micropore   analysis options. Carbon   dioxide   adsorption,   conducted   at   0   deg   C   using   a   dedicated   iso-thermal   control   unit,   provides for   fast   and   accurate   micropore   size,   volume   and   area   determination.   It   is   especially   effective   as   a   low- cost   rapid   screening   option   for   highly   microporous   materials   where   a   high   throughput   is   demanded whilst retaining excellent resolution. Gas    adsorption    isotherms    can    also        be    combined    with    mercury    porosimetry    to    investigate    the complete range of micro pores through to macro pores.   For   the   generation   of   accurate   pore   size   distribution,   pore   volume   and   pore   area   data   it   is   imperative   that samples   are   degassed   prior   to   analysis.   MCA   Services   can   accommodate   a   wide   range   of   conditions   for   this which   may   be   combined   to   suit   the   individual   requirements   of   our   clients.   Degassing   temperatures   up   to 200˚C   under   vacuum   or   400˚C   with   flowing   nitrogen   or   helium   gas   can   be   applied.   This   is   usually   conducted at MCA Services immediately prior to analysis as part of our standard procedure.
