## Abstract A method for isotachophoretic determination of sweeteners of different character in candies and chewing gums was developed. A capillary of 0.8 mm ID and 90 mm effective length made of fluorinated ethylene‐propylene copolymer is filled with an electrolyte system consisting of 10 mM HCl +
The utility of three various analytical techniques [ion chromatography (IC), capillary electrophoresis (CE) and isotachophoresis (ITP)] was tested in the determination of counter‐ions in synthetic peptides. The analyzed ions were acetates, trifluoroacetates and chlorides. IC provided the best result
