    Direct Atomic Absorption Spectrometric determination of Se in Biological Fluids by Graphite Filter Furnace Atomizer with Graphite Thread
    (2016) Zacharia, Oleksandr N.; Arabadzhy, Mykhayl V.; Chebotaryov, Oleksandr M.; Seref, Gucer; Захарія, Олександр Миколайович; Чеботарьов, Олександр Миколайович
    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.

    Graphite filter furnace atomizer as effective tool for direct atomic absorption analysis of some biological materials
    (2015) Zacharia, Oleksandr N.; Arabadzhy, Mykhayl V.; Chebotaryov, Oleksandr M.; Захарія, Олександр Миколайович; Чеботарьов, Олександр Миколайович
    It is well known that electrothermal atomic absorption spectrophotometry (ETAAS) are widely used for the determination of the total trace elements concentration in various biological samples. However, at these several drawbacks, especially its macro components interference effect on the atomic absorption value of the elements to be determined, as well as non-specific absorbance of light, must be taken into account. In recent years not only Stabilized Temperature Platform Furnace (STPF) technique for elimination of a number of interferences, but graphite filter furnace (FF) atomizer has been shown to be a very powerful tool for quantitation of Pb, Cd and Cu in organic-based materials. Unfortunately, in analytical practice of toxicological, medical and other corresponding laboratories for ETAAS analysis of serum, whole blood, urine and other biologicals this device are not practically used.
