Sažetak
Optimization procedures in Ion Chromatography require unambiguous goals. Optimization criteria express such goals in mathematical terms. If the retention factor tR, varies as a function of the parameters to be optimised criteria should be selected that enable simultaneous optimization of retention and selectivity. The non – suppresed Ion Chromatographic method with conductometric detection is described for simultanious determination of six inorganic anions: fluoride, chloride, nitrite, bromide, nitrate and sulphate. It is demonstrated that the result of optimization process depends on the optimization criterion selected. The computer-simulated chromatograms were used for the comparison of optima calculated using four different criteria. General recommendations for double criteria optimization of separation in ion chromatography are suggested. v
