AU168: Determination of Transition Metals in Complex Matrices

Instrument Type: IC

Chelation ion chromatography facilitates the determination of low concentrations (μg/L and lower) of transition metals in samples including seawater, brines, estuarine waters, and a variety of biological samples. Here, the authors simplify the system configuration described in Technical Note 25, using an ICS-3000 system. The separation has also been updated to include the IonPac CS5A/CG5A column set, which demonstrates improved selectivity and peak efficiency for separation of transition metals compared to the CS5.
