CHROMATOGRAPHIC SEPARATION PROCESS AND SEPARATOR

摘要

A method for chromatographic separation wherein components contained in a liquid feedstock or the like are separated by passing the feedstock through a packing layer which is regulated in the degree of separation between the components by using two or more kinds of packings different in the degree of separation between the components in an intermingled state, thus giving fractions enriched in the components respectively at high purities and high recoveries with a decreased amount of use of the desorbing agent such as eluent; and equipment for chromatographic separation wherein three or more components can be separated by using a first packing exhibiting a high degree of separation between a medium-affinity component and a weak-affinity one and a second packing exhibiting a high degree of separation between a strongaffinity component and a medium-affinity one in an intermingled state to regulate the degree of separation of the packing layer between respective two of the three components, thus giving three or more fractions enriched in the respective component.
