Theory behind chromatography
WebbIon Chromatography- Theory. Ion Chromatography is a method for separating ions based upon their interactions with resin (stationary phase) and the eluent (mobile phase). These phases differ between an anion … WebbThe theory was integrated into the chromatography technique in 1941 by Martin and Synge. According to the model, the chromatographic column consists of separate layers known as the theoretical plates. These plates are hypothetical zones or stages that help in establishing an equilibrium between two phases.
