A Micromeritics Autopore III mercury porosimeter can be used to measure the percolation characteristics of your samples. It measures the porosity and void size distribution from calculating a two dimensional approximation assuming a series of aligned cylinders, with sizes based on the Laplace equation. The maximum applied pressure of mercury for the porosimeter is 414 MPa (60 000 psia), equivalent to a Laplace throat diameter of 0.004 µm.

We use our own computer software 'Pore-Comp' to correct for the compression of mercury, expansion of the glass sample chamber or 'penetrometer' and compressibility of the solid phase of the sample. We also use our software 'Pore-Cor' to develop a three dimensional structure from the mercury porosimetry intrusion curve.
