Microchip Electrophoresis:A New Platform for Metal Speciation

摘要

Metal speciation is of considerable interest to the scientific community,due to the significant roles played by individual metal species in biomedicine and in the environment.Microchip electrophoresis,as specifically applied to metal speciation,is reviewed here.The review covers microchip-based determinations of metal cations (directly),metal cations as complexed species using laser induced fluorescence,absorbance (LED) and chemiluminescence detection,oxidation states,and the speciation of simultaneously existing metal complex species.Rapid microchip analysis clearly opens up the potential for species distribution analysis of environmentally and biologically important metal complexes.
