Multi-criteria decision making development of ion chromatographic method for determination of inorganic anions in oilfield waters based on artificial neural networks retention model

► Development of ad hoc methodology for anions determination in oilfield water. ► Artificial neural networks were used for modeling of anion retention in IC. ► Optimal networks were used for retention predictions in 47775 virtual experiments. ► Multi-criteria decision making was used for determination of optimal separation. ► Optimal method was finally validated and applied for real oilfield water sample.
