TL;DR: It is suggested that retention parameters, in particular the capacity factor obtained by extrapolation of retention data from binary eluents to 100% water, could successfully replace the n-octanol-water partition coefficient in studies on quantitative structure-activity relationship, and that their use may result in a better correlation with biological data.

TL;DR: In this article, the effect of temperature in liquid chromatography on pyrocarbon-containing adsorbents is considered in terms of heats of transfer, solvent eluotropic strength, column linear capacities, pressre drops and efficiencies.

TL;DR: In this paper, the retention behavior of chlorinated phenols during electrokinetic chromatography with micellar solutions and open-tube capillary columns was investigated, and the capacity factor for each compound of a test mixture was calculated by considering both the effects of mousellar solubilization and electrophoresis of the ionized solute, even when a solute was ionized.

TL;DR: In this paper, the chiral separations of the neutral enantiomers of chlorthalidone by packed capillary electrochromatography was successfully achieved using two approaches: (a) use of chiral agent, hydroxypropyl-β-cyclodextrin (HPβCD) directly in the mobile phase with an achiral stationary phase (3 μm ODS), and (b) using of a chiral stationaryphase (5 μm HPβCD-bonded silica particles) with an chiral mobile phase.

TL;DR: In this paper, a micellar electrokinetic capillary chromatographic (MECC) system, containing sodium dodecyl sulfate and a buffer, is shown to extend the elution range and thus increase the peak capacity of a given system.
Abstract: The addition of 1–20% (v/v) of methanol or acetonitrile as organic modifier to the mobile phase in a micellar electrokinetic capillary chromatographic (MECC) system, containing sodium dodecyl sulfate and a buffer, is shown to extend the elution range and thus increase the peak capacity of a given system. Although the net change in the elution range parameter, to/tmc, is essentially the same for both modifiers, the acetonitrile-modified system exhibits much faster elution times for the polar and non-polar test solutes employed in this study. Retention, as measured by the capacity factor, is generally decreased with the increase of an organic modifier, just as in conventional reversed phase chromatography. However, changes in selectivity as a function of the added modifiers are noted among polar and non-polar solutes as well. The efficiency of these MECC systems is increased with the addition of either organic modifier.
