ALBANY, New York – XOS announces the installation of its 1,000th SINDIE 7039 sulfur analyzer. This analyzer was installed at the Yanshan refinery of the China Petroleum & Chemical Corporation (the Sinopec Corporation).

With this milestone, SINDIE analyzers have been sold to hundreds of customers in 33 countries and throughout the United States.

This announcement builds on XOS’s steady growth in the energy sector. “From the time that we launched production of the first-generation SINDIE analyzer to the shipment of this 1,000th unit, the SINDIE product line has earned a reputation as an indispensable analytical instrument for today’s energy companies,” said Berry Beumer, Vice President of Sales and Marketing at XOS. “This latest milestone affirms XOS’s commitment to leading-edge technology solutions that address analytical challenges which support the success and productivity of the global energy sector.”

The energy sector demands state-of-the-art detection performance, reliability, and ease-of-use from its materials analysis tools, and SINDIE analyzers help XOS’s customers monitor sulfur content with unrivaled accuracy in such diverse fuels as crude, biofuels, gasoline, and ultra-low sulfur diesel (ULSD).

SINDIE offers unique advantages with a measurement technique based on Monochromatic Wavelength Dispersive X-Ray Fluorescence, or MWDXRF. The practical application of this technology in the SINDIE product line enables energy and transportation companies to meet clean-air mandates enforced by global regulators. In turn, this reduces sulfur-oxide exhaust emissions that are responsible for producing acid rain and causing adverse health and environmental conditions.

Sinopec received recognition of this milestone at its refinery in Yanshan, China. According to executives at Sinopec, “We are very proud of becoming the 1,000th user of the monochromatic wavelength x-ray fluorescence sulfur analyzer made by XOS. The analyzer has demonstrated significant performance advantages over other commonly used methods, such as coulometry, UV fluorescence, and conventional x-ray fluorescence. These advantages include high detection precision, high analysis speed, ease-of-use, high stability, and low maintenance. The analyzer has received wide acclaim from operators and technical staff during the course of operation. In particular, the refinery division of the Sinopec Yanhua Company recently received high-octane fuel components, which required high-analysis precision and speed. The XOS sulfur analyzer demonstrated excellent performance during the analysis process, and made a heroic contribution in successfully completing the factory quality assurance analysis. Please let us thank XOS and its distributor in China, Phase Analytical, for providing us with an analyzer of outstanding performance.”

In a related development, Phase Analytical Solutions was given XOS’s Asia Distributor of the Year Award in recognition of Phase’s outstanding customer and technical support in the China market.

Other features of XOS’s SINDIE product line that make this milestone significant include:

• The SINDIE product line serves diverse market segments such as petroleum production, refining, and distribution; petrochemicals; biofuels; enforcement; independent testing; and power generation.

• End-users include refinery labs, pipeline and marine terminal operators, enforcement authorities, and third-party test labs.

• XOS spearheaded the ASTM D-7039 standard development covering the SINDIE measurement method, and the company maintains the task group chair for measuring sulfur in fuels.

• Regulators worldwide recognized D-7039 for the purpose of certifying sulfur in fuels.

• A portable version of the SINDIE benchtop analyzer –SINDIE On-the-Go (OTG) – received Instrument Business Outlook’s 2009 Industrial Design Award for portable instruments.
