Abstract
The present invention relates to a chromatographic separation process for fractionating betaine-containing solutions by utilizing fractions comprising parts of the separation profile as a substituent of the eluent in a novel and inventive manner. The process provides improved separation capacity and separation efficiency without affecting the yield or purity of betaine or other products. The process can especially be applied to sequential SMB separation systems.
