The aim of this work was to study the various electrolyte systems in which hydroxycarboxylic acids can be separated by capillary isotachophoresis. Using ß-cyclodextrin as additive to the leading electrolyte, the complete separation of hydroxycarboxylic acids was achieved. The results confirmed the significant influence of the cyclodextrin concentration and pH on the resolution of hydroxycarboxylic acids.
