WebRetardation factor. In chromatography, the retardation factor ( R) is the fraction of an analyte in the mobile phase of a chromatographic system. [1] In planar chromatography in particular, the retardation factor RF is defined as the ratio of the distance traveled by the center of a spot to the distance traveled by the solvent front. [2] WebThe integrated continuous downstream process starts with crude cell lysate and consists of a flow through chromatography step followed by periodic counter current chromatography (PCC) (bind ...
