Technical Information: Pore Size Distribution Measurement Method
Introduction to pore size distribution measurement methods such as "gas adsorption method" and "mercury porosimeter"!
Typical measurement methods for the pore distribution of powders and functional materials include gas adsorption methods and mercury porosimetry. The "gas adsorption method" primarily analyzes N2 or Ar gas adsorption isotherms at low temperatures (liquid nitrogen or liquid argon), allowing for the measurement of pore diameters ranging from molecular size to several hundred nanometers. The "mercury porosimeter" is a method that involves applying pressure to mercury, which is not easily wetting to the material, and determining the pore distribution from the amount forced into the sample. Additionally, in recent years, methods such as "gas permeation" and "bubble point method" have been developed to measure only the permeable pores of filters and separation membranes.
