Physical adsorption webinar - A materials characterization technique for determining the surface area, porosity, and total pore volume of solids
(Nanowerk News) The fourth in Micromeritics' ongoing series of live webinars highlighting applications, theory, and instrumentation showcases a thorough examination of the Physical Adsorption materials characterization technique. This informative webinar will be broadcast at both 9:00 AM and 11:00 AM EST on Thursday, June 24th.
Surface area and porosity are important physical properties that influence the quality, utility, and handling of many materials, which often must be carefully engineered to perform specific functions. Differences in the surface area and porosity of material which otherwise may have the same physical dimensions, can greatly influence its performance characteristics. Therefore it is critically important that these characteristics be accurately determined and controlled.
Physical adsorption is a technique used to characterize the surface and pore features of solids, that is, the materials texture. The adsorption isotherm generated by the Physical Adsorption technique enables one to characterize a solids' texture by determining its surface area, porosity, and total pore volume.
In this presentation, the Physical Adsorption technique is defined, theory discussed, and real-world examples of the usage of this technique for characterizing surface and pore features of solids are presented.
