Description
Summary:In order to develop methodology for the simple recognition of samples that are very similar by ion-chromatographic analysis, 116 different Slovenian water samples, of known composition, were considered. Suitable dilutions and appropriate detector output ranges for the ion-chromatographic determination of sodium, magnesium and calcium were predicted. These data were related to data on the chemical composition of each individual water sample, expressed in mequiv.%. A triangular diagram was designed. This is a sort of ion chromatographic map that enables institutions dealing with the periodical checking of numerous different samples to recognize the most similar samples easily and allows for the very fast and efficient transition from traditional to ion chromatographic analysis. The accuracy of the predictions was checked experimentally.
