ABSTRACT:
The invention provides a multistage membrane system for the recovery of solvents and solutes from chromatographic systems, including first means for directing a first fluid stream of a main eluting fraction, containing target molecules to be concentrated and solvent, to a first filtration membrane unit for concentration and recovery of the target molecules at the feed side of the first membrane; second means for directing fluid streams of other eluting fractions of the chromatographic process, containing contaminants and solvent, to a second filtration membrane unit for concentration and collection of the contaminant solutes at the feed side of the second membrane unit; and third means for directing filtered solvent coming from the permeate side of the first filtration unit to the feed side of the second filtration membrane unit, whereby the filtered solvent intermixes with the fluid stream of other eluting fractions.
