Sažetak
This work focuses on development of ad hoc methodology for monitoring of sodium, ammonium,
potassium, magnesium and calcium ions in rivers Ilova and Kutinica (southeastern part of Croatia)
since often their composition significantly differs from the average (concentration of components and/or
matrix). Therefore fast and reliable method development has to be performed in order to meet criteria of
the monitoring methodology performance characteristic. Computer assisted routine for prediction of
chromatographic signal, based on a transfer of isocratic elution information into a gradient elution environment,
was used in combination with several in-house developed optimization criteria. It is shown
that algorithm used for prediction of ion-chromatographic signal offers sufficient information (in comparison
to actual measured chromatographic signal) to be applied in global optimization process. Calculated
optimal gradient incorporates linearly decreasing, increasing and isocratic part of the eluent concentration
time-profile, utilizing full potential of the gradient separation. Developed method was validated proving
that it meets criteria for river Ilova and Kutinica monitoring purposes. Moreover, this results show that
used computer assisted optimization routine can be successfully applied for fast and reliable ad hoc
method development in ion chromatography. (doi: 10.5562/cca1736)
