Özet:

 

After sample vaporization in two-step atomizer with a purged
vaporizer sample vapors can be transferred into preheated or into non-heated
atomizer. In the last case the atomizer walls trap the vapors and then the
sample is second time vaporized and atomized by heating the atomizer.
Thermal pre-treatment of a sample using this double vaporization makes
possible the direct analysis of samples with strongly interfering matrices
including solids. The technique was used for the direct determination of Cd
and Pb in human urine, high concentrated water solutions of NaCl, Na2SO4,
NaNO3, KH2PO4 and NH4H2PO4 matrices, potatoes, wheat, bovine liver,
milk powder, grass-cereals mixture, caprolactam, bituminous-shale and
polyvinyl chloride plastic without chemical modification or any other sample
pre-treatment.
