Surface Properties Analyses by Gas Adsorption and Mercury Intrusion Methods

Abstract

Specific surface area and pore size distribution are effective to evaluate the surface properties of toner and its composition materials, especially nano-scale structure overall. It differs from immediate information seen with the microscope etc., and averaged data on the entire sample can be obtained efficiently. Gas adsorption method and mercury porosimetry are both typical techniques effectively used for the measurements of specific surface area and pore size distribution.
In this text, it explains an outline, an analytical method of these two techniques, and the application limit, etc.
