An automatic on-line preconcentration system for graphite furnace atomic absorption spectrometty (GFAAS) for the determination of trace metals in sea water was developed. This system was modified from a Perkin-Elmer AS-40 autosampler by mounting a silica gel Crs microcolumn near the tip of the autom
ea water, like other high-salinity matrices, causes severe interferences in the direct determination of metals by graphite furnace atomic absorption spectrometry (GFAA ), even when Zeeman-effect background correction is applied. A method for eliminating these interferences by the application of mixe
