Procedures for the direct determination of total selenium in urine, serum, and blood using electrothermal atomic absorption spectrometry are presented. In the selected experimental conditions, Zeeman correction is mandatory to compensate for the high background signals. The sample diluted and contai
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
