Tests of the consistency between binary gas adsorption isotherms and. binary chromatographic retention volumes

The amounts of two gases simultaneously adsorbed on a solid can be measured directly or may be inferred from chromatographic retention times. Adsorption isotherms obtained by the two methods should agree within experimental error. It is desirable to have a quantitative test of the degree of agreement between experimental results made by both methods. We establish here a new adsorption function and relationship that should exist between the measured retention times and static data if both methods and the experimental results are in perfect agreement. This function gives a test of consistency between static data and retention times that has advantages over alternative methods.
