Inductively Coupled Plasma - Optical Emission Spectroscopy (ICP-OES) has been an important technique in the petroleum/petrochemical analysis laboratory since the 1970s due to its ability to determine a range of elements and concentrations in both aqueous and organic samples. Additionally, because ICP is compatible with many organic solvents, it permits the preparation of a wide range of sample types using only a simple dilution.
This application note will demonstrate the ability of the Teledyne Leeman Labs Prodigy7 ICP-OES to determine a range of elements in petroleum samples. By combining the Prodigy7’s high sensitivity and dispersion with appropriately chosen wavelengths and background correction points, accurate and reliable results can easily be obtained for a suite of elements.
