Abstract
Liquid chromatographic processing of compositions containing ionizable compounds. The chromatographic column is formed of a stationary packing having a chemical group chemically bonded thereto and a counter ion is added to the polar mobile liquid. The counter ion forms a reversible complex with at least one characterizing radical of at least one of the ionizable compounds.
