In this paper, ionic chromatography technique was evaluated to motivate its use in research and graduate studies in water sciences. Water samples were analyzed by both conventional techniques and HPLC and it was found that ionic chromatography generates less than a half of waste material than conventional techniques, wastes that are less toxic and with a level of concentration of µg/L Also, when HPLC is used, the costs are reduced by a factor of 3.5, the average time diminish from 3 days to 4 hours and the experimental errors are lower. The results show that ionic chromatography is a fast, economical, sensitive and reliable analytical technique that can be performed by trained students, not requiring highly specialized personnel.
