Analytical Instrumentation
Focus on XRF Analysis
Proven and Reliable Route to Ensure Essential Compliance for Low Sulphur Analysis Meeting and Exceeding ISO 20847, ASTM D4294 and ASTM D2622 Specifications
Oxford Instruments (UK) provides market leading, simple, robust, easy to use, field proven analytical solutions for sulphur analysis; for crude oil extraction, refineries, terminals, independent testing houses, shipping, customs and excise and even at point of retail. Oxford Instruments has a range of analysers for measuring sulphur in oil at every point it is needed along the supply chain, and over 40 years of experience.
Starting with the Energy Dispersive XRF (EDXRF) Lab-X3500 which is a compact bench-top analyser that can be used in the lab, in the field, in a mobile laboratory, in fact where ever you need on site analysis, operated by production staff and with full conformance to ASTM D4294. The EDXRF X-Supreme8000 offers multi-sample analysis for “ultra low sulphur” (<10ppm) up to 5% using just one calibration line for all sample matrix types. In addition, the X-Supreme8000 has the flexibility of additional elements such as nickel vanadium in fuel oils; manganese in gasoline, etc.
The Wavelength Dispersive XRF MDX1000 offers simultaneous elemental analysis conforming to ASTM D2622. For sulphur in oil, reliability is achieved through employing two fixed monochromators; thereby avoiding any moving parts. All of the above instruments are world renowned for long term reliability and ease of use. This is achieved through close attention to detail on high quality design and manufacture learned over many years. For example one major component is the X-ray tube manufactured by Oxford Instruments in the US and used in their EDXRF instruments. The above instruments can help improve compliance and the accuracy of analytical results.
As well as advanced technology systems for space, Oxford Instruments Industrial Analysis offers a range of Analytical Instruments designed for demanding quality control applications. From materials analysis to thickness gauging, the Industrial Analysis products incorporate the latest in available technology, coupled with over 50 years of experience in designing, producing and supporting world class instruments. X-MET handheld X-ray Fluorescence (XRF) analysers and the expanded range of Optical Emission Spectrometers (OES) are specifically designed for positive material identification, alloy analysis and the determination of hazardous materials for RoHS compliance. The OES systems comprise: Foundry- Master Pro, Foundry-Master Compact and UV, together with a mobile range including Pmi-Master Pro, Test Master Pro and the ARC-MET8000.
Lab-X, Twin-X and MDX1000 XRF spectrometers span the price/performance range for routine chemical analysis. From Sulphur in petroleum products to the analysis of limestone,
Oxford Instruments can match the correct spectrometer to the consumers needs, as the range is extremely broad. For thickness gauging applications they offer handheld magnetic and eddy current gauges to full function, high performance XR systems. Our X-Strata980 and CMI900 systems provide world-class performance for coating thickness measurement.

Ultra Low Sulphur Analyser in all Fuels, Biofuels and Oil, Compliant with ISO 20847 and ASTM D-4294
Horiba (France) is proud to release the SLFA 3000 series of ultra low sulphur analyser for biofuels, gasoline and petroleum products. It is compliant with current recommended methods: ASTM D4294 - 08a Standard Test Method for Sulphur in Petroleum and Petroleum Products by Energy Dispersive X-ray Fluorescence Spectrometry and ISO 20847:2004 specifies an energy dispersive X-ray fluorescence (EDXRF) test method for the determination of the sulfur content of motor gasoline, including those containing up to 2.7% (m/m) oxygen, and of diesel fuels.
With the new analyser, the typical detection limit is 2 ppm which is much below the lowest regulated content of sulfur (10 ppm). While a good detection limit is very useful, the crucial problem with energy dispersive X-Ray fluorescence is the matrix effect. Major developments for the new instrument are automatic matrix corrections with sophisticated algorithms and innovative spectrum analysis. Thanks to these new and unique features, the SLFA 3000 automatically makes matrix corrections for a wide range of sample C/H ratio (from 7 to 9) as well as for oxygen content up to 34 %.
So ultra low detection limits and matrix correction enable these analysers to be an essential tool for all type of products: From 0 - 10% S in sour crude to sweet crude to straight run gasoline to reformulated gasoline, etc… SLFA 3000 is your partner for pipeline, refinery or independent test laboratories with its short measurement times, extremely simple use and accurate, reliable results. It is the last member of the large Horiba Sulphur in Oil analyser family. It is the high end model of the EDX series including SLFA 2100/2800 for standards fuels, and the very famous SLFA-20 which the very compact and light model for “everywhere” analysis. For traces or very low sulphur levels, the SLFA- UV21A, based on combustion and SO2 analysis using UV fluorescence method, is completing the range. It can also analyze the nitrogen. It is compliant with ASTM-D5453 and ISO 20 846.

Expanded Partnership for XRF Specialists
Based on the successful relationship that began with the MESA 6000 EDXRF Analyser, Innov-X Systems, Inc. and Horiba Instruments (both USA) are pleased to announce their expanded marketing partnership. Horiba will now market the Innov-X X-50 and X-5000 fluid analysers for applications analyzing elemental content in petrochemical and hydrocarbon fluids. The X-50/5000, manufactured by Innov- X, combines the analytical power and safety of a closed-beam benchtop XRF system with battery operation port - ability. The result is a unique XRF system that utilises either a silicon PiN diode (X- 50) or silicon drift detector (X-5000) and a high powered 50 kV, 10 Watt x-ray tube. The X-5000 measures elements from Mg to U in a variety of hydrocarbon samples and petro - chemical fluids, whereas the X-50 measures from S to U. Both models feature a specially designed sample holder to consistently locate either bottles or XRF sample cups for fluid sample analysis.
“We are very pleased to extend this partnership” said Innov-X Business Development Manager Suzanne Moller. “Innov-X has been very successful with the X-50/5000 product family in their traditional portable XRF markets such as environmental, mining and mineral exploration. Extending our marketing partnership with Horiba allows us to reach the petrochemical and hydrocarbon analysis markets for this product.” The X-50 and X-5000 will be sold through the existing Horiba sales channels for the petrochemical and hydrocarbon fluids applications.
Rudy Haas, Horiba’s Oil Products Business Manager stated, “Horiba is proud to partner with this group of talented and innovated engineers and excited to bring these compact analyzers to the marketplace.”
