Golubitskii, E. Budko, E. Basova, V. Ivanov] An isocratic and a gradient elution mode of HPLC are compared in the analysis of five multicomponent pharmaceutical formulations. It is shown that in some cases, these modes have no advantages over each other in the precision of the peak areas of components if sample solutions are injected successively. In other cases, the results of the gradient elution are more precise. Pleiades Publishing, Ltd., 2007 Golubitskii G.
