The Admittance Concept in the Kinetics of Chromatography

Abstract
Chromatographic processes with linear kinetics can be represented by a system admittance for the case where the influent concentration varies sinusoidally. The admittance has been obtained for a variety of assumed rate controlling mechanisms and is shown to depend strongly on the type of kinetics obeyed by the system. The results indicate experimental techniques for determining the kinetics of these processes. Representative results obtained with an electronic analogue computer are presented for a case of non‐linear kinetics.
