Graphite filter furnace atomizer as effective tool for direct atomic absorption analysis of some biological materials

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.
