Application of the zeeman effect to analytical atomic spectroscopy-III Extension of calibration curves.
An application of the Zeeman effect is described by which calibration curves applicable to high analyte concentrations may be obtained. The procedure uses single-beam measurements on the displaced sigma-components of the Zeeman multiplet, and thus permits controlled desensitization of an atomic-absorption signal to be obtained, simply by increasing the magnetic field strength, while leaving the monochromator permanently set on the optimum analytical line for the element considered. Calibration curves for Ca, Cd and Cu are given for applied field strengths from 0 to 16kG.
