Analytical method for determining desorption isotherm and pore size distribution of an absorbent material

摘要

A method is provided for generating data for use in calculating a desorption isotherm for an adsorbent material as well as a pore size distribution characteristic of the adsorbent material by flowing an adsorbate gas over a sample in a cell until the surface of the sample is saturated with the adsorbate, shutting off the flow of the adsorbate gas and then flowing a carrier gas through the cell to remove the adsorbate material from the surface of the sample while continuously detecting and recording per unit of time the composition of the gas mixture flowing from the cell and the sample temperature until only the carrier gas is detected.
