WebMultimodal or mixed-mode chromatography (MMC) incorporates multiple modes of chromatography in a single resin. This enhances the selectivity of the resin because proteins can be separated based on several of their characteristics, rather than just a single one. MMC is of great value in cases where other resins cannot provide sufficient resolution. WebFeb 27, 2024 · Capillary electrochromatography (CEC) is a separation technique that hybridizes liquid chromatography (LC) and capillary electrophoresis (CE). The selectivity offered by LC stationary phase results in rapid separations, high efficiency, high selectivity, minimal analyte and buffer consumption.
