The   porosity   of   geological   samples   if   often   of   critical   interest   to   many   fields   of   geology,   for   example   geochemistry,   environmental   and engineering   geology,   hydro-geology,   petrology,   and   both   conventional   and   unconventional   energy   etc.   The   pore   volume   and   pore   size distribution   characteristics   is   often   of   primary   influence   top   the   physical   properties   of   rock   samples   and   the   flow   and   retention   behaviour of fluid through them.  Key Techniques BET Surface Area - including krypton adsorption for low area materials Mercury Porosimetry - for pore size, pore volume & pore area distribution Mercury Porosimetry - for cavity to throat size evaluation Permeability and Tortuosity measurement via Mercury Porosimetry & Pycnometry Gas Adsorption - pore size, area  and volume distribution in the mesopore range Micropore Analysis - pore size, area and volume distribution Density measurement - absolute density, bulk density & skeletal density Measurement of Total Pore Volume Specific probe gases, e.g. H2, CO2, O2 etc available for adsorption capacity measurement    MCA   Services   offers   a   complete   suite   of   techniques   for   the   characterisation   of   material   porosity   throughout   the   range   of   micropores, through   mesopores,   to   macropores.   We   also   have   the   experience   and   expertise   to   actively   assist   with   interpretation   of   results   and   gain maximum    benefit    through    application    of    state-of-the-art    software    to    obtain    highly specialised report and graphical formats. P orosimetry   techniques   have   been   applied   to   geological   samples   of   high   porosity,   such   as sandstones   and   chalks,   through   to   relatively   non-porous   materials   such   as   tight   shales. The    techniques    have    also    been    of    considerable    benefit    in    evaluating    the    effects    of treatments on construction materials, such as concretes and ceramics. The     application     of     mercury     intrusion     porosimetry,     in     combination     with     helium pycnometry,   is   particularly   suited   to   the   measurement   of   the   permeability   of   geological samples.   Further   combination   with   BET   surface   area   also   allows   for   the   assessment   of tortuosity.   These   techniques   provide   for   relatively   rapid   measurement   with   the   additional benefits of providing the pore size, volume and area distributions of the samples. As   the   possibilities   of   extraction   from   shale   increase,   so   too   does   the   interest   in   their characterisation.   Analysis   of   pore   size   and   pore   area   distributions   provides   critical   data   in   the   assessment   of   their   storage   capabilities. Pore   sizes   are   typically   <   2μm,   often   with   a   significant   distribution   in   the   mesopore   range.   Mercury   porosimetry   provides   a   powerful analytical    tool    for    measuring    of    pore    volume    and    area    distribution,    sample    density    and    cavity    to    throat    size    characteristics.    Gas adsorption   provides   complete   mesopore   distributions   and   the   extension   to   dedicated   micropore   analysis   if   micropore   volume   and   area distributions   are   required.   Specific   probe   gases,   such   as   carbon   dioxide,   hydrogen   and   oxygen   can   also   be   applied   to   evaluate   adsorption capacity.
