Energy Dispersive X-ray Fluorescence (EDXRF) is a fast, simple, and non-destructive elemental analysis technique for the measurement of liquids, powders, and solids. It is widely applied throughout the petroleum industry: upstream at the well site, mid-stream at pipelines, storage facilities and blending operations, and down-stream at the refinery. In 2017, the US Environmental Protection Agency (EPA) implemented new regulations on the composition of fuel, which included changing the maximum allowable sulfur content from 30 parts per million (ppm) on an annual average basis down to 10 parts per million (ppm). With more stringent requirements, better tools and technology are needed to test the sulfur content of fuels, namely, gasoline and diesel. The EDXRF is the ideal analytical tool to accurately determine the sulfur content in fuel samples, conforming to not only ASTM D7220, but also meeting the requirements for the EPA Tier 3 program.

Furthermore, the EDXRF can be used to determine concentration of some elements such as manganese, lead, zinc, phosphorous, and calcium. The determination of manganese and lead content gives an indication of the anti-knock agent added to motor gasoline and Avgas to improve octane rating.  Whilst the determination of zinc, phosphorous, calcium, and sulfur give an indication of the antioxidant, and anti-wear agents in lubricating oils. This poster discusses the versatile application of the EDXRF which allows end-users to effectively ascertain correct results for this desired use, and conform to international testing standards.
