Abstract
An acyclic Zeeman effect atomic absorption spectrometer viewing the sample analyzed continuously and simultaneously with two linear orthogonally polarized radiation beams preselected as to wavelength to effectively cancel out, upon logarithmic ratioing of their electrical analogs, the contribution of adulterants to the mass determination of a trace element in analysis and thereafter obtaining the ratio of the integrated value of the monitored sample logarithmic ratio signal with that of a stored standard sample integrated logarithmic ratio signal as a measure of the concentration of trace element present.
