Chromatography method and device, in particular method and device for supercritical liquid chromatography

Abstract

This version will replace all prior versions in the application: A chromatography method in which a starting material is separated into fractions and at least one of the fractions which have at least a predetermined target content of at least one target component of the starting material is derived as a target product fraction. The fractions which do not have the predetermined target content form residual fractions and at least part of at least one of the residual fractions is added to the starting material still to be separated. At least part of at least one of the residual fractions of which the content of the target component differs less from the predetermined target content than the target component content of the starting material is added to the starting material still to be separated. The residual fractions of which the target component content differs more from the predetermined target content than that of the starting material are diverted for further handling.
