Capillary Electrophoresis in Determination of Low Molecular Mass Organic Acids

 Abstract—This paper presents overviews the capabilities of capillary electrophoretic techniques to determine low molecular mass organic acids in a variety of aqueous, gas and solid samples. It mainly focuses on short - chain carboxylic acids containing one or more carboxylic groups and possibly some other functional groups (hydroxyl, keto-, amino- etc.). Finally the procedures applied to the determine the acids in different matrices are shortly characterized. The principles of capillary electrophoresis its advantages over gas and liquid chromatographic separation and detection modes are briefly discussed. Finally, the brief overview of the technique is followed by characterization of CE based procedures for the analysis of a variety of samples such as food, environmental, biological etc. for the content of organic acids, mainly those with carboxylic groups.
