Electroinjection analysis: Concept, mathematical model and applications

Electroinjection analysis is described and compared with electrophoretically mediated microanalysis and flow injection analysis. Mathematical models of electroinjection analysis and electrophoretically mediated microanalysis are presented. An analytical solution for the concentration of the product of a chemical reaction is derived and used for the discussion of the optimal regimes of analysis. Examples of the applications of electroinjection analysis and electrophoretically mediated microanalysis for the determination of Cr(VI) and Co(II) ions in water are presented.
