Patent attributes
A cyclic chromatographic purification method for the isolation of a product from a feed mixture consisting of the product and at least one further component representing impurities, which impurities bind stronger to the chromatographic stationary phase than the product is given. The method uses at least two chromatographic adsorbers as chromatographic stationary phase, grouped into only one first adsorber section (1) and one second adsorber section (2), wherein if an adsorber section comprises more than one chromatographic adsorber these are permanently connected in series, wherein the first adsorber section (1) has a first adsorber section inlet and a first adsorber section outlet, and the second adsorber section (1) has a second adsorber section inlet and a second adsorber section outlet.
