Abstract

Throughput of organic solvent aerosol to the flame of an atomic absorption spectrometer may be controlled by varying the position of the impact bead relative to the nebulizer, instead of varying the solution uptake rate of the nebulizer. The usefulness of this simple technique has been demonstrated for a range of elements in three organic solvents (4-methylpentan-2-one, xylene, and a high-boiling-point iso-paraffin solvent), with air/C₂H₂ and N₂O/C₂H₂ flames. It is shown that the adjustment of the impact bead alone allows the determination of high concentrations of copper and iron in lubricating oils without undue dilution of the sample and can result in significant improvements in the speed of analysis.
