Electroinjection analysis has been demonstrated to provide reaction kinetics information. Reactants are injected continuously from opposite ends of the capillary for the duration of the experiment, and reaction product formation occurs at the boundary where the zones merge. The width of the product signal measured by the detector depends on the ratio of the fluxes of reactants. The boundary moves toward the detector where the products are measured. A sharp peak at the edge of the main flat product signal peak was observed and most probably corresponds to the metastable intermediate product of reaction, a unique capability of this technique. A theoretical explanation and an experimental verification of the possible use of electroinjection analysis for the study of reaction kinetics is given.
