Measurement of gas adsorption isotherms by continuous adsorbate addition

Abstract

A technique of measuring gas adsorption isotherms by continuous addition of adsorbate gas to the sample is described. Flow rates in the range of 0.01-1 mL (STP)/min can be obtained by means of orifices with diameters of 1-10 μm. The continuous-flow technique is compared with the customary incremental addition of the adsorbate gas for two sorbents, a γ-alumina and a high volatile bituminous coal.
