WebJan 18, 1991 · The term counter-current chromatography usually refers to the process in which one liquid phase is maintained by gravitational or centrifugal forces as a stationary bed, distributed longitudinally in a column, while a second immiscible liquid phase flows through the stationary bed. WebThis paper presents a theoretical and practical approach for designing a periodic counter-current chromatography (PCC) operation as a continuous capture purification step that is integrated with a perfusion cell culture process. The constraints for continuous and optimal PCC operation govern the selection of residence time and number of columns.
