S6 JAGUAR - Analysis of Lead in Gasoline - ASTM D5059 Method A and C

Adding Lead (Pb) to gasoline seemed to be a great enhancement, when first discovered in the 1920's. Early concerns about environmental and health safety began shortly after. Finally, Pb in gasoline is now absent from common fuel in most of the world. Some aviation and specialty fuels however still use Pb and need to report the concentrations. Additionally, it sometimes is required to test for Pb in gasoline to make sure it is below the regulated limits.

The ASTM Standard Test Method D5059 describes how to measure high (0 - 5 g Pb / US gal) and low (0 – 0.30 g Pb / US gal) levels of Pb in gasoline with XRF spectrometry using Bi as an internal standard.

The WDXRF spectrometer S6 JAGUAR is equipped with Bruker’s 400 W HighSense™ X-ray tube. This makes the S6 JAGUAR the most powerful benchtop WDXRF unit on the market! Modern software with built-in audit-tracking and state-of-the-art hardware enables best-in-class analytical performance. The S6 JAGUAR achieves outstanding sensitivity for a wide range of elements (F to U) and the various configuration options allow us to optimise the system for your needs.

When using the S6 JAGUAR for gasoline analyses, you get the full power of a WDXRF system that fits in a benchtop unit. Especially when measuring only a few elements, the S6 JAGUAR is an excellent fit. In contrast to other methods like AAS (Atomic Absorption Spectroscopy) and ICP-OES (Induced Coupled Plasma – Optical Elemental Spectroscopy), a simple one-time calibration makes the S6 JAGUAR ready for your application.

The S6 JAGUAR is an ideal choice for liquid sample analysis:

• Dedicated liquid cups for simple and rapid loading of liquid samples
• SampleCare™ technology, protecting critical system components for low maintenance
• (optional) Cup-in-cup technology for additional protection
• Intuitive software SPECTRA.ELEMENTS with “one button” solutions
• Sturdy design and robust, high quality components for long lifetime
• (optional) Ergonomic TouchControl™ display for operation without PC peripherals

The S6 JAGUAR has a wide range of capabilities and this report demonstrates that it is reliable for analysis of Pb in fuels. The system easily fulfils the requirements for the WDXRF norm ASTM D5059 method A and C. The WDXRF spectrometer brings several advantages to your lab, when compared to AAS and ICP-OES, including lower costs of operation and minimal calibration effort.

The S6 JAGUAR enables time-efficient and accurate monitoring of additives, contaminants, and wear metals in fuels, lubricating and engine oils. When installed at refineries and oil-production plants, it can easily test the quality of incoming materials and optimise the used additives from day one. It ensures that all elements in fuels are analysed at best performance with highest accuracy and precision combined with low cost of ownership.
