The separation was carried out in a neutral coated capillary. Separation was performed at 14 kV of applied potential. Temperature was maintained at 20 C. The background electrolyte used was 200 mM phosphate buffer at pH 7.50. Separation was obtained in less than 13 min. Validation parameters obtained for the method permit it to be considered adequate for routine analysis.application/pdfenopen accessCapillary electrophoresis.Carboxylic acids.Short-chain organic acid.UV.Wine.Artículohttp://creativecommons.org/licenses/by-nc-nd/4.0/deed.eshttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es
