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
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
Palladium was determined in pharmaceuticals by direct graphite furnace atomic absorption spectrometry (GFAAS) method. The detection limit was 0.1 mg/g in 5% solution; the recovery of 0.5-2.0 mg/g Pd spike was close to 100%. The flow injection GFAAS method was worked out using oxime and iminodiacetic
