The separation of multicomponent mixture by displacement development is fully analyzed by applying the theory of multicomponent chromatography. With Langmuir isotherms it is possible not only to elucidate all the characteristic features of the process but also to derive analytic expressions for the critical value of the developer concentration and the plateau concentration as well as the width of each pure component band attained at the ultimate stage. A specific example demonstrates that the actual solution at the ultimate stage is identical to that predicted a priori by using these expressions. The bed length required for complete separation is determined by examining the wave interactions involved. This procedure is clearly illustrated.
