Characterization of structures by gas adsorption of porous carbon and silica utilizing for electrode, conductive substances and catalyst materials will be the subject of this web seminar. The evaluation of pore structure from N2 and Ar adsorption isotherms will be explained with an overview of each analysis theory and measurement examples. Specifically, the evaluation methods of specific surface area for inner and outer pore and these pore volume by t and alpha-s method and pore size distributions of micropores by adsorption potential theory and mesopores by capillary condensation theory will be explained with graphical representation.
In addition, we will introduce a new product BELSORP MAXII-HP/HV, a high accuracy gas/vapor adsorption instrument.
