A displacement chromatography process, including: loading onto a stationary phase comprising an anion-exchange material a mixture comprising one or more component to be separated; n displacing at least one of the one or more component from the stationary phase by applying to the stationary phase a mixture comprising an polyaromatic polyanionic displacer compound having a general formula Cen (Ar) w , in which Cen is a central bond or group, Ar is an aromatic nucleus, w=2 to the maximum number of sites one Cen, and Ar is substituted with a plurality of An − , in which each An − is independently defined as sulfonate, carboxylate, phosphonate, phosphate, sulfate; and Ar is further substituted with a plurality of G, in which G is defined as independently H, C 1 -C 6 alkyl, halogen, nitro, hydroxy, C 1 -C 6 alkoxy In addition, a group of polyaromatic polyanionic displacer compounds useful in the process is disclosed. |
