The traditional widespread method for the atomic-absorption spectral analysis (Walsh's method) now is consecutive since demands use of the selective light source and reorganization of wavelength of the monochromator for definition of each element as a part of test. This fact seriously reduces analysis productivity, however, this method almost completely excludes emergence of the problems connected with spectral hindrances.Using a method of the atomic-absorption spectral analysis with a continuous spectrum source and a spectrometer with low resolution for the simultaneous analysis of multielement samples, spectral hindrances of analytical lines of the elements which are contained in the analyzed substance are inevitable. For carrying out the correct qualitative and quantitative analysis it is necessary to identify, to divide and to consider spectral hindrances. In this work we presented application of a method of identification and accounting of spectral hindrances on a spectral complex of low resolution "Kolibri-AAS".
