Any solid material that contains cavities, channels or interstices may be regarded as porous Porosity influences the physical exchanges and chemical reactivity of solids with gases and liquids. Porosity is of great industrial concern as it influences the behavior of gas adsorption and fluid flow within materials. Examples of materials that porosity is of importance include catalysts, construction materials, ceramics, pharmaceutical products, metal powders, membranes, active components in batteries and fuel cells, and oil and gas bearing reservoirs. With a large selection of gas sorption analyzers, along with mercury intrusion instruments, Micromeritics offers a product to fulfill almost any need for porosity determinations. Available Techniques: – Gas sorption – Mercury intrusion porosimitry (MIP) – Pycnometry
