Analysis of Fe, Ni, Cu, As, Cd and Pb in edible oils

This application study was designed to demonstrate the performance of the Epsilon 5 EDXRF spectrometer and to show that the instrument meets the analytical challenge of analyzing Fe, Cu, Ni, As, Cd and Pb in edible oils. The long term stability and precision of the instrument is also demonstrated.

The refining processes for products such as edible oils require the addition of catalysts in the correct proportions to optimize the processing reactions. These catalysts also contain elements such as Ni and Fe that must be removed from the oils during the later stages of the refining process.
