Abstract
A method of analyzing the characteristics of an adsorbent is provided. The method uses a sample chamber of known volume and known temperature with an adsorbent to be analyzed. An adsorptive gas which comprises at least 80 percent of a component gas and less than 20 percent of a carrier gas, at a temperature higher than its boiling point at environmental atmospheric pressure is introduced into the sample chamber. The pressure of the adsorptive gas is measured. The quantity of the adsorptive gas adsorbed by the adsorbent, at the measured pressure is determined. And, a relative pressure in the sample chamber and the quantity of the adsorptive gas adsorbed by the adsorbent at the relative pressure is correlated.
