Abstract

It is shown that the modified sequential simplex algorithm can be used as the basis for the unattended optimisation of reversed-phase liquid chromatographic separations. A chromatographic response function is computed to evaluate individual chromatograms with respect to resolution and analysis time. This function is used automatically by a microprocessor-controlled chromatograph to optimise experimental parameters. The use of the procedure is illustrated by the automated optimisation of two and three component mobile phases and the optimisation of a gradient elution profile.
