DEFINITION
Classification: 210/672
Fractional, selective, or partial type:
(under subclass 670) Process in which only a portion of a static body of ion exchange or sorbent material is regenerated, or parts of the body are regenerated to different levels of activity; in which two or more components of the original liquid, deposited on the ion exchanger or sorbent, are removed separately from the insoluble material by an eluant and collected in fractions containing varying proportions of the components; or in which two or more components are removed separately by the use of an eluant specific for the removal of each, e.g., selective elution.
