  • Title: Analysis of water-soluble vitamins by micellar electrokinetic capillary chromatography.
    Author: Fujiwara S, Iwase S, Honda S.
    Journal: J Chromatogr; 1988 Aug 05; 447(1):133-40. PubMed ID: 3209661.
    Abstract:
    Seven water-soluble vitamins were determined simultaneously by micellar electrokinetic capillary chromatography with UV detection. All these compounds were separated from each other within ca. 22 min by using a carrier containing sodium dodecyl sulphate as the surfactant. On-column detection at 254 nm with ethyl p-aminobenzoate as the internal standard allowed sensitive, accurate and reproducible determination of these compounds. Five principal constituents of a vitamin injection were determined with relative standard deviations of less than 2.1%.
