Amino phases can be run in the RP mode using aqueous organic eluent mixtures as well as in the NP mode, e. g., with hexane as mobile phase. Also anion exchange chromatography of anions and organic acids using common buffers (e. g., acetate or phosphate) in conjunction with organic modifiers (e. g., acetonitrile) is possible.
