Abstract
A theoretical estimate is presented of the background correction error in electrothermic atomic absorption spectrometry with modulation of the coefficient of atomic absorption in an alternating magnetic field. The experimental results for the background absorption induced by scattering of radiation are in good agreement with theory. Substantial additional distortions in the output signal due to interaction of molecular vapor with the graphite surface arise in the case of a molecular background.
