Ion exchange

Keyword Definition

Ion exchange chromatography (or ion chromatography) is a process that allows the separation of ions and polar molecules based on their charge.  In the early 1970s, ion chromatography was developed at Dow Chemical Company as a novel method of IEC usable in automated analysis. This later led to the formation of Dionex Corp (Dow -Ion Exchange).  IC uses weaker ionic resins for its stationary phase and an additional neutralizing stripper, or suppressor, column to remove background eluent ions.
