WebPore size distribution is a key factor when characterizing porous materials. For example, surface area and porosity are important properties in the field of catalyst design. Total surface area is vital for the performance of solid catalysts since it dictates the number of active sites on the surface of the catalyst. The pore size, pore size ... Capillary flow porometry, also known as porometry, is a characterization technique based on the displacement of a wetting liquid from the sample pores by applying a gas at increasing pressure. It is widely used to measure minimum, maximum (or first bubble point) and mean flow pore sizes, and pore size distribution of the through pores in membranes nonwovens, paper, filtration and ultrafiltration media, hollow fibers, ceramics, etc.
