The determination of metals in traces by means of electrothermal atomization atomic absorption spectrometry (ETA-AAS) presents analytical difficulties for complex matrixes such as seawater or brines. Some of them can be overcome with sample pretreatment or through the use of matrix modifiers at the
Optimum operating conditions have been determined for the atomization of zinc from metalloproteins in a graphite furnace. Addition of 50 mM ammonium dihydrogen phosphate to the protein and measurement of the integrated absorbance suppresses or eliminates matrix interference effects. Using a 5-~1 sam
The optimized measurement of Cr in urine samples using graphite furnace atomic absorption spectrometry, with a tungsten lamp and Zeeman-effect background correction is described. Sample dilution and slow hot injection were studied in an effort to improve the precision. Parameters such as detection l
