Abstract

Atomic magneto-optical rotation spectroscopy (AMORS) based on the Faraday effect was applied to direct determination of trace amounts of copper, manganese and chromium in samples containing complex matrices: The NBS Orchard Leaves, the NBS Bovine Liver, mandarine orange juice and volcanic ashes. Suspensions of powder samples and diluted juice were pipetted into a graphite tube atomizer and atomized directly or after mild charring. One of the AMORS’s inherent advantages is the insensitivity to background scattering caused by non-atomic species which is generated from sample matrix on atomization. This facilitates analyses by direct atomization. Such an advantageous feature of AMORS is exemplified in the practical analyses.
