Silicon Analysis in Petroleum and Bio Fuels


 From gasoline to ethanol and toluene, the Signal bench-top analyzer delivers unprecedented precision and accuracy in quantitative analysis of silicon. The analyzer is based on XOS’s MWDXRF technology platform (as applied in Sindie and Clora analyzers) ensuring a robust analysis solution for demanding petroleum and industrial environments.

With the recent release of ASTM D7757, it won’t be long before your customers start asking:


“What’s the silicon level in your fuel?”

Silicon (Si) contamination continues to impact fuel quality, resulting in costly engine failures and catalyst fouling. ASTM test method D7757 uses proven, state-of-the-art technology to provide exceptional Si analysis.

Know the contamination sources and develop working solutions.

Understand the impacts of Si contamination on your business.

Determine your Si baseline for future specifications set by ASTM or the end user.

The main features of the Sindie-7039 bench-top analyzer include:

Direct measurement without sample conversion; Analysis in ppm (wt)

LOD : 0.4 ppm

Dynamic Range: 0.15 ppm to 3000 ppm

Outstanding linearity: One calibration for diesel and gasoline matrixes over full dynamic range

Fast measurement time: 300 seconds

No consumable gases required

Extremely low maintenance

XOS Introduces the SIGNAL Analyzer

Better Silicon Detection Counts


December 21, 2010 – XOS (USA) announces its latest product introduction – the Signal analyzer – featuring XOS’s robust, widely used Monochromatic Wavelength Dispersive X-Ray Fluorescence (MWD XRF) to detect Silicon down to 0.5 ppm with the XOS-exclusive advantage of unprecedented precision at the push of a button.  Signal effectively eliminates extensive sample preparation associated with ICP while offering better precision in a 10-minute measurement cycle:  Placing the sample in a standard XRF sample cup is the only handling required for the measurement.   This Silicon quantification capability is available for petroleum matrices, additives and bio-fuels, including ethanol.  XOS’s MWD XRF platform technology is also used in the company’s award-winning Sindie and Clora line analyzers to quantify  Sulfur and Chlorine in hydrocarbon, aqueous and bio-fuels matrices. “XOS is leading the ASTM D2.03 Task Group for the development of an ASTM standard test method for the Signal technology, and a wide ranging inter-laboratory study has been completed in support of this ASTM method development effort,” said Berry Beumer, Vice President of Sales and Marketing at XOS.

altMWD XRF uses state-of-the-art focusing and monochromating optics to increase excitation intensity and offers a dramatic improvement of signal-to-background over high-power traditional WD XRF instruments.  This enables significantly improved detection limits and enhanced precision from crude oils matrices to bio-fuels.   MWD XRF is a direct measurement technique that does not require sample treatment or sample conversion and does not involve high-temperature operations or processing.
