A hybrid method was suggested for preconcentration of trace metals and removal of matrix elements in seawater samples. In this method; seawater samples were loaded off-line into the syringe-driven chelating columns (SDCCs); which were then connected to a valve-switching system for on-line elution and on-line determination of Fe; Cu; Ni; and Zn by ID-ICP-MS. Optimizations of operating conditions were carried out for sample loading flow rate and pH. The removal of matrix elements was not carried out; because the concentrations of Mg; Ca; Na; and K were sufficiently low when 5 mL or less of the seawater sample was used for analysis. The usefulness of the present method was confirmed by analysis of NASS-5. Detection limits for Fe; and Zn were 0.03; 0.012; 0.018; and 0.009 ng mL-1; respectively. © 2009 The Royal Society of Chemistry;
