Ion exchange ph
WebIon exchange chromatography exploits the relationship between net surface charge and pH to create reversible electrostatic attraction of charged molecules to the stationary phase, which has covalently attached side groups of opposite charges, to achieve separation between each species (Fritz, 2004). WebThe strong ion exchange phases are called “strong” because the sulfonate cation or quaternary ammonium anion exchange group remain charged over the entire pH range. …
