Comparitive Invesitgations of Several Sources of Light for Atomic Absorption Spectral Analysis

Abstract The dependence of the Intensity and the half-width of several spectral lines on the discharge current and the radiation power has been studied. The experiments have been carried out with spectral lines of Zn, Cd, Na, Pb and Hg, radiated by different sources of light (hollow-cathode lamps (HCL) with d.c. power supply; electric discharge lamps (EDL) with h.f. power supply; metal-vapour discharge lamps (MVDL) with a.c. power
