—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.
