    Reproducibility of migration times and propagation of error in micellar electrokinetic chromatography (1992)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Microcolumn Separations 4 (1992), S. 399-404 
    Details
    ISSN: 1040-7685
    Keywords: micellar electrokinetic chromatography ; electroosmosis ; migration time reproducibility ; propagation of error ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The contributions of several factors (electroosmosis, capacity factor, and elution range) to migration time reproducibility have been evaluated using the theory of error propagation. Experimentally obtained values confirm that a single factor, electroosmosis, can explain most of the observed variability.

    Micellar and microemulsion electrokinetic chromatography of hop bitter acids (1996)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 19 (1996), S. 189-192 
    Details
    ISSN: 0935-6304
    Keywords: Micellar electrokinetic chromatography (MEKC) ; Microemulsion electrokinetic chromatography (MEEKC) ; Hop acids ; Separation mechanism ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The elution order of the hop α- and β-acids has been studied under different modes of electrokinetic separation. A model is advanced to explain the shorter migration times of the more hydrophobic β-acids compared to the α-acids in micellar electrokinetic chromatography (MEKC). For quality control of the bitter principles in hops, the ruggedness of electrokinetic separation could be improved by replacing MEKC by microemulsion electrokinetic chromatography (MEEKC).
