Ion chromatography is a type of high performance chromatography method for the multicomponent analysis of compounds of an ionic nature or those that, under certain conditions, are capable of ionization. The method as a whole repeats the ideology of HPLC, but low-capacity ion-exchange columns and dilute eluents are used, which determines a number of systemic methodological and instrumental differences.
The ion chromatograph is constructed from functional modules, each of which is constantly improved to achieve the best result. Modern pumps achieve excellent flow accuracy over a wide range of speeds.
