The method covers “the quantitative determination of additive elements in unused lubricating oils and additive packages,” and is now complete with a repeatability and reproducibility statement, notes Dirk Wissmann, Senior Product Manager XRF, SPECTRO Analytical Instruments GmbH.
SPECTRO XEPOS energy dispersive X-ray fluorescence (ED-XRF) spectrometers — which feature new developments in excitation and detection that deliver outstanding sensitivity and detection limits and yield remarkable gains in precision and accuracy — are compatible with ASTM D7751 – 16, Wissmann states.
A new brief, addressing the topic of the new method, discusses the XEPOS analyzer and five key applications for the elemental analysis of petrochemical products. Titled, "Analysis of Twenty-Four Elements in Petrochemical Products," the brief examines applications from the blending control of fresh lubricants and the control of additive packages to used oil analysis; sulfur in crude oil distillates and sulfur and other trace elements in crude oil and heavy fuel oil; and distillate burner fuels derived from waste mineral oils. The brief is available at http://xrf.spectro.com/spectro-xepos/application-briefs/analysis-of-elements-in-petrochemical-products.
Also available is the on-demand webinar, "Elemental Analysis of Liquid Petroleum Products with a Focus on ED-XRF.” The webinar presents an overview of the different elemental analysis techniques that can be used for petrochemical products. The webinar can be accessed at http://xrf.spectro.com/spectro-xepos/on-demand-webinars/elemental-analysis-of-liquid-petroleum-products/.
SPECTRO XEPOS spectrometers represent a dramatic advance in ED-XRF technology. They feature breakthrough advances in the multi-elemental analysis of major, minor, and trace element concentrations and are compatible with the new “ASTM D7751 – 16” standard test method.
