Micellar electrokinetic capillary chromatography of amoxycillin and related molecules.
A micellar electrokinetic capillary chromatographic method has been developed for the qualitative assay of amoxycillin and its degradation products and clavulanic acid. Together with amoxycillin the latter acid is an important constituent in the antibiotic Augmentin. The analytical procedure is fast and analytes can be identified both from their migration times and from changes in migration time observed either at different pH values or in electropherograms run in H2O and D2O based buffers of the same acidity.
