Abstract: The formation of the signal of the blank as well as of the analytical signal for the atomic absorption analytical signal for the atomic absorption spectrometry with the electrothermal atomization is along with the electronic properties of the detection and registration equipment of the spectrometer, similarly conditioned hy the purity of. the used chemicals as well as by the spectrochemical matrix effects. Each signal is the complex one, and it is composed of the element-specific component and the component conditioned by the background. The detailed study of such complex signals is necessary as these conditions in influence the evaluation parameters of the method, especially the detectability and the analytical calibration. The analytical calibration for the determination of the trace elements in water matrixes itself is significantly conditioned by the presence of the major and minor element components in the analyzed waters.
