About ion chromatograph : What is ion chromatography?

Ion chromatography is positioned as a type of liquid chromatography that measures ionic species components. This method separates ion species components in a sample solution in a packed column using an eluent as the mobile phase and an ion exchanger as the stationary phase.
Electroconductivity detectors are commonly used to detect ionic species, but for some purposes, ultraviolet-visible spectrophotometry and electrochemical detectors are used as well as liquid chromatography.

Ion chromatography is an analytical method that is used in a wide range of fields, such as quality control for environmental water and wastewater, as well as air quality measurement and quality control in the food field, in view of its ability to perform simultaneous multi-component analysis and its difficulty in being affected by coexisting components.
In addition, in addition to inorganic cations and anions, the components to be measured include lower amines, heavy metal ions, organic acids, and saccharides, and the scope of application has expanded.
