    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.

    Alcohol modifiers in MEKC with SDS as surfactant. Study on the influence of the alcohol chain length (C1—C12) (1996)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 19 (1996), S. 674-678 
    Details
    ISSN: 0935-6304
    Keywords: Micellar electrokinetic chromatography (MEKC) ; Organic modifiers ; Alcohols ; Chain length ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The influence of alcohol modifiers with different chain length on the migration time window in micellar electrokinetic chromatography (MEKC) has been studied. Highly polar alcohols like methanol and 1-propanol are typical aqueous phase modifiers. Higher alcohols like 1-butanol, 1-pentanol and 1-hexanol influence the micellar structure and are considered as micellar phase modifiers. The effect of long chain alcohols is small because of their low applicable concentrations.
