A Non-Dispersive AMOR (Atomic Magneto-Optical Rotation) Analyzer for Multielement Trace Determination

Abstract

A non-dispersive AMOR (atomic magneto-optical rotation) analyzer was tentatively con structed for multielement analysis and its analytical performance was examined for deter minations of Mg and Zn. The hollow cathode lamps of Mg and Zn were modulated at different frequencies. The source radiations from the lamps were merged by a grid mirror. The rotatory radiation emerging from the optical system in the Faraday configuration was received by a solar-blind photomultiplier tube. The signals of Mg and Zn were separated by the fast Fourier transformation (FFT) processing.
