ABSTRACT:
Peak resolution in reversed-phase electrochromatography is improved in either of two alternative ways. The first is by a stepwise increase in the concentration of acetonitrile or other equivalent buffer constituent or modifier after the sample has been loaded, and the second is the inclusion of a surfactant in the mobile phase.
