| Abstract: | Based on that the absorbance is proportional to the effective length of the absorbing layer of atoms, a simple foumula is derived by which the atomization efficiency. Two atomization efficiencies were calculated: beta1 and beta2, which gave the fraction of calculated the total number of analytical atoms that enter the analysis volume during each stage of atomization. It is based on two different calculated ways for the mean residence time of atoms, and the beta1 and beta2 values of Ga and Tl in furnace with V-boat in various atomization temperatures were determined. Influence of the loss process of atomic vapor on the atomization efficiency value was discussed. |
