“…Before each injection the capillary was washed first with a solution of sodium hydroxide (0.01 M, 1 min), then with a solution of sodium tetraborate (10 mM, pH 9.3, 1 min) [25], and finally with the electrolyte (3 min).…”

SummaryIon-exclusion chromatography (IEC) and capillary electrophoresis (CE) have been compared for determination of organic acids in samples of Sherry wine vinegar. The accuracy of each technique was evaluated by use of the standard addition method. There were no differences belvveen the techniques at a significance level of 5%, except for determination of malic acid by CE. Both analytical methods were used to analyse sixteen samples of Sherrywine vinegar supplied by different producers. The regression coefficients (r ~) for analysis by IEC and CE exceeded 0.94 for all acids. Results from both methods were in good agreement and the methods are sufficiently selective and sensitive to be applied directly to sherrywine vinegars.

“…For routine analysis it is essential to keep the migration times constant in order to allow automatic peak identification by means of commercial data analysis software. Automatic peak identification and quantification are only possible if the relative standard deviation of migration times is less than 0.5% [55]. Several reviews have been published which describe the improvement in the reproducibility of the results [55][56][57][58][59][60][61].…”

The chiral resolution of the environmental pollutants by capillary electrophoresis is reviewed. Various aspects of the chiral resolution such as chiral selectors, optimization of capillary electrophoresis conditions including composition of the background electrolyte (BGE), pH of the BGE, ionic strength of the BGE, structures and types of the chiral selectors, applied voltage, temperature, structures of the chiral pollutants, use of organic modifiers and other parameters are presented. Furthermore, detection, sample treatment, validation of the methods, and the chiral recognition mechanisms, have been discussed.

“…The reproducibility of migration times and peak areas strongly depends on the capillary rinse procedures between each run in CZE system [12]. Capillary rinsing can make the system return to the initial running conditions, so the influence of the EOF variation is reduced [13][14].…”
