Separation and determination of cations in beverage products by capillary zone electrophoresis

Separation and determination of inorganic cations in beverages by capillary electrophoresis with indirect UV detection

“…8A, 8B and Table 3). As can be seen, the data obtained by CE are in good agreement with those from atomic absorption (except NH 4 + which cannot to be determined by AA). Fig.1 Table 2.…”

“…The determination of beverage cations is one of the most important for their routine quality control [4,21,22]. Real samples of jasmine tea and coconut milk were examined by the proposed method (Figs.…”

“…It yields highly efficient separation, good repeatability, simple operation, and rapid detection, along with very low consumption of electrolyte and sample [6][7][8][9][10]. It has been successfully used to separate 14 cations in beverages [4]. Fritz et al [5] reported using a complexing electrolyte to separate 27 cations.…”

Separation and Determination of Six Metal Cations by Capillary Zone Electrophoresis

“…In this study, malonic acid of 8 mmol·L + and Mn 2+ cannot be complete baseline separation by using malonic acid only. Some papers reported [16,19,20] that the addition of crown ether (18-crown-6 ether) could improve the selectivity. For improving the separation between K + and Mn 2+ ions we investigated the effect of 18-crown-6 ether on the separation showing in Figure 2.…”

“…The use of capillary zone electrophoresis for the analysis of cations in water samples has been studied [8][9][10][11][12]. In recent years, although many instrumental analysis have been used in environmental water samples, such as ion chromatography (IC) [13], atomic absorption spectroscopy (AAS) [14], as well as inductively coupled plasma combined with mass spectrometry (ICP-MS) [15], the capillary zone electrophoresis holds the promise of even better separations and lower sample consumption [16]. Simultaneous determination of copper, cobalt and cadmium, manganese and lead were found to be influence by the derivative spectrophotometry [17].…”
