Abstract
LATERAL diffusion in the gas phase as well as sorption–desorption kinetics may both influence the plate height of gas-solid chromatography. While the complicated nature and alignment of adsorbing surfaces in a column cannot be fully described mathematically, a model is presented here which allows for the fundamental diffusion and reaction processes of gas-solid chromatography. The theory is written in a general form which can be readily extended to more complex phenomena. The adsorption isotherm is assumed linear, a condition recently made practical by highly sensitive detectors.
