The porous nature of geological samples and construction materials is often critical in the understanding of their performance behaviour and suitability for a wide variety of applications. 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  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. 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. Porosimetry techniques have been applied to geological samples of high porosity, such as sandstones and chalks, through to relatively non-porous materials such as basalts. 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.
