This technical note describes chelation concentration, a selective concentration method, coupled directly to an ion chromatograph for the determination of transition metals in complex matrices. This method, Chelation Ion Chromatography, combines analyte concentration and matrix elimination with analytical separations and sensitive detection for transition and lanthanide metals. The result is a chromatographic technique that permits trace and ultratrace determination of metals in variety of sample matrices, especially those high in alkali and alkaline earth metals.
