Fast determination of cations in honey by capillary electrophoresis: A possible method for geographic origin discrimination

► A fast CE method for cations determination in honey samples was optimized and validated. ► Peakmaster® software was used to optimize the BGE composition. ► Under optimized CE conditions, separation of five cations was achieved in less than 2 min. ► The method applied to fourty honey samples, which were diluted and filtered before injection. ► PCA confirmed that the cation content is strictly linked to geographical origin of samples.
