Ion Exchange Chromatography

High performance in the separation of organic substances by liquid chromatography had already been achieved by the 1970s, while techniques of chromato-graphic separation of inorganic ions were developed to a lesser extent. In 1971, the first papers dealing with automatic spectrophotometric detection of metal ions separated by ion exchange chromatogra-phy on cation exchange resins appeared. Similarly, anions were separated on anion exchange resins. Conductometric detection was established by Small et al. in 1975 and Gjerde et al. in 1979. Finally it is necessary to mention ion exclusion chromatography applied to separate sugars and carbonic acids with an ion exchange column, but without any ion exchange interaction.
