Info

Type I Pores are typically microporus with the exposed surface residing almost exclusively inside the microspores, which once filled with adsorbate, leave little or no external surface for further adsorption.
Type II Most frequently found when adsorption occurs on nonporous powders or powders with diameters exceeding micropores. Inflection point occurs near the completion of the first adsorbed monolayer
