Efficiency and resolution of ion chromatography is greatly influenced by the choice of the proper chromatographic column. These differ in their dimensions, capacity, structure of the stationary phase, ion exchange groups, maximal allowed mobile phase flow and for which purpose the manufacturer made them. There are many different manufacturers which make parts for ion chromatography and therefore there is a lot of different commercially available chromatographic columns one can choose from. In my undergraduate thesis I made a literature review of research articles and the analysis of different chromatographic columns which were used by their research work. From specifications and test chromatograms which are given by the chromatography column manufacturers I tried to make a comparative analysis of columns suitable for determining citrate and calcium and magnesium in complex matrixes.
