The theoretical‐plate concept in chromatography has been treated on the basis of continuous flow of eluent through the plates of the column. A treatment more precise in principle than the previous treatments is presented. General elution and deposition equations have been derived and applied to special cases of practical interest. The derived formulas have the advantage of precision, generality, and simplicity. The theory was found adaptable to the treatment of gradient elution and also to the calculation of the fraction of solute which has been eluted or still‐adsorbed on the column during the elution process. A method for the determination of the number of theoretical plates in a chromatographic column is also described.
