    Theory of field-flow fractionation with the reversible adsorption on channel walls (1993)
    Springer
    Chromatographia 37 (1993), S. 325-328 
    Details
    ISSN: 1612-1112
    Keywords: Field-flow fractionation ; Reversible adsorption ; Peak broadening ; Peak asymmetry ; Mathematical model

    Topics: Chemistry and Pharmacology
    Notes: Summary The particle-wall interactions in field-flow fractionating channels are described phenomenologically using the distribution coefficient, k. The time dependencies of the first and second dispersion coefficients are calculated and compared with the known solutions for the case of no adsorption. The results for the retention ratio and peak broadening are compared with the known experimental work. The model predicts the increase of peak broadening with the growth of particle-wall interactions that is consistent with the experimental data. The dependence of peak asymmetry on transverse Pe number and distribution coefficient is studied.

    On the mathematical model of capillary electrophoresis (1993)
    Springer
    Chromatographia 37 (1993), S. 202-210 
    Details
    ISSN: 1612-1112
    Keywords: Electrophoresis ; Electroosmosis ; Mathematical model ; Peak Broadening
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary The influence of the electroosmotic flow profile on the efficiency of capillary electrophoresis for a wide range of buffer concentrations and capillary diameters is studied. Thermal effects in the capillary, the finite size of solute molecules and their interactions with the capillary wall are also taken into consideration. The dependence of capillary electrophoresis efficiency and resolution on the zeta-potential values is investigated.
