Electrothermal atomic absorption spectrometry (ET AAS) is one of the most effective methods (tool ) for the direct determination of Se in biological fluids (blood, urine, saliva and breast milk and other) that is important for studying of element effect on human body status as well as at diagnostic some of diseases. Although ET AAS method offers high sensitivity and require low volume of sample to be analyzed, however Se determination can cause significant difficulties from spectral and matrix interference effect as well as serious risk of it losses during the sample preparation stage. For solving these problems the “filter furnace atomizer” (FFA) with graphite thread (GT) and Pd-Mg chemical modifiers (CM) are appears as promising tools for the direct ET AAS analysis materials with a high content of organic matter [1-4]. Unfortunately, in analytical practice of clinical, toxicological and etc. laboratories it is not widely used.
