Semicontinuous affinity chromatography separations.
The semicontinuous operation of affinity chromatography columns charged and eluted alternately is studied mathematically. A strongly nonlinear adsorption equilibrium relation is utilized to examine the periodic mode of adsorption and desorption. The governing differential equations are solved by the method of characteristics. The time interval between desorption and adsorption periods is estimated, and implications for separations are discussed to show the advantages of semicontinuous cyclic operation.
