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 fufill almost any need for porosity determinations.

Improved design, effectiveness and performance of catalysts require an in-depth understanding of the surface structure and surface chemistry of the catalytic materials. Chemisorption is utilized to determine a catalyst’s efficiency in promoting a desired reaction as well monitoring the degradation of catalytic activity/regeneration over time.

Chemisorption is used to quantitatively measure the number of surface active sites which are used to promote a specified catalytic reaction. Critical parameters for chemisorption measurement are: the area of the active element, metal dispersion, surface acidity, exposed proportion of the active element.
