Patent ID: 7361273

Claim:
A chromatographic separation method for separating a component from at least one other component in a solution comprising a mixture comprised of said component and said at least one other component, wherein said component and said at least one other component are selected from the group consisting of arabinose, rhamnose, glucose, xylitol, erythritol, inositol, mannitol, glycerol and betaine; wherein the method comprises at least one chromatographic separation step with a weakly basic anion exchange resin for separating said component from said at least one other component wherein said step comprises feeding said solution into a chromatographic column filled with the weakly basic anion exchange resin having an average particle size of 100-2000 micrometers, eluting said column with water and recovering a product fraction or product fractions, where the content of said component is higher than in the solution fed into the chromatographic separation step.
