WebFirst, let’s consider polarity and the two primary separation modes that exploit this characteristic: normal-phase and reversed-phase chromatography. Separations Based on Polarity A molecule’s structure, activity, and physicochemical characteristics are determined by the arrangement of its constituent atoms and the bonds between them. WebIn multimodal chromatography, the choice between bind/elute and flowthrough mode is more complex than when using a single method, such as IEX, because multiple types of interactions are occurring in multimodal chromatography, and the strength of these individual interactions often depends on the overall process conditions.
