Ion chromatography or Ion exchange chromatography is a branch of High-Performance Liquid Chromatography or HPLC. It has a potential of separating charged molecular species present in the mobile phase stream. In simpler words, you can also say that it is a method used for separating any compound’s ions on the basis of their interaction with stationary (resin) and mobile (eluent) phase. The process consists of two columns named anion column and cation column that attract anions and cations, respectively. By separating these ionic species, one can measure their concentrations in the given substance.
