Abstract

This article describes the determination of vanadium in crude oils, iron in pitch, and titanium in polypropylene. The sample is placed into a pyrolytically coated graphite microboat and pyrolyzed in an air-acetylene flame. The microboat is then inserted into the cuvette of a flameless atomizer, and the sample is atomized at a temperature up to 3400°C.
