Comparison of the analytical performance of flame atomic magneto-optic rotation spectrometry in the Faraday configuration with that of flame atomic absorption spectrometry

Abstract

Atomic magneto-optic rotation spectrometry (AMORS) is an analytical technique for the determination of elements and has much in common with AAS. This paper compares the analytical performance of the two techniques for several elements using flame atomization. Using the same instrumentation for all measurements, Mg and Ag were studied in depth by AAS and AMORS. The best AMORS results were obtained when the angle between the planes of polarization of the polarizing and analysing prisms was ± 45°. Under these conditions the detection limits and linear ranges were slightly better than those obtained by AAS.
