Mixed-mode stationary phases such as Atlantis BEH C18 AX offer unique selectivity and are complementary to existing RP stationary phases making them valuable for column screening during method development. In addition to the ability to retain ionized acids, Atlantis PREMIER BEH C18 AX Columns can also produce sharp, symmetrical peaks for protonated bases and should therefore be considered when developing chromatographic separations for numerous types of compounds, whether they be polar acids or hydrophobic bases, like umifenovir.
