Since its introduction in 1975 ion chromatography has been used in most areas of analytical chemistry and has become a versatile and powerful technique for the analysis of a vast number of inorganic and organic ions present in samples with different matrices. Nowadays, ion chromatography has almost completely displaced the classical methods of ions determination. The main advantages of ion chromatography include the short time needed for analyses, possibility of analysis of small volume samples, high sensitivity and selectivity, and a possibility of simultaneous separation and determination of a few ions, or ions of the same element at different degrees of oxidation. Taking into account the above advantages ion chromatography is routinely used for the analysis of ionic compounds in water, air and soil samples. The most important aims in ion chromatography development are new stationary phases, enhanced peak capacity through the use of complex eluents profiles, new methods of sample preparation and implementation of hyphenated methods. Ion chromatography will continue to develop as more and more ionic contaminants become regulated at increasingly lower limits in the future. This paper shortly describes the history, principles, development and applications of ion chromatography.
