Computer software
that allows the simulation of any chromatographic separation as a function of
simultaneous changes in any one or two variables that can affect sample separation
order (selectivity) is described. For one example, an application is described
for the simultaneous variation of the mobile phase pH and gradient time in reversed-phase
liquid chromatography. The accuracy of such predictions is examined for a sample
mixture of 17 substituted benzoic acids and anilines, and requirements for an
acceptable predictive accuracy are summarized. In a second example, the separation
of three peptides by capillary electrophoresis is optimized.
