A proprietary Inductive Coupled Plasma – Optical Emission Spectroscopy (ICP-OES) sample preparation protocol has been developed by scientists at Warwick Analytical Service (WAS) allowing regular, reproducible detection of sulfur at trace levels of only tens of parts-per-million (ppm). After trialling various sample weights, WAS scientists were able to determine a suitable measure to give the most accurate results. They found that a larger volume of sample was more suitable but not so large that the microwave digestion process was incomplete. The ICP conditions used for low level Sulfur determinations typically requires a high purge for over an hour with the nebulizer and coil power set to axial view.For a copy of an application report describing the new Sulfur protocol in more detail please contact.
