New Sulfur Certified Reference Materials for Petrochemical Testing

Emily Withers, Marketing, Paragon; Matthias Nold, Product Manager Reference Materials

Paragon logoParagon Scientific is a UKAS accredited company specializing in the manufacture of Certified Reference Materials (CRMs) for petrochemical analysis. These products complement our broad portfolio of high-quality certified reference materials.

A comprehensive range of sulphur standards suitable for the most common internationally recognized test methods has now been added to this portfolio.

Background

Petroleum, or crude oil, is a valuable commodity because it is the feedstock for a wide range of products from fuels to plastics. Sulfur and its organic compounds are impurities found in crude oil, petroleum products and feedstock. The sulfur levels in these products vary from the highest amounts in the crude oils to trace levels in fuels.

Sulfur oxides formed during the combustion of gasolines or diesel fuels in internal combustion engines are damaging to the engine and to the environment. In the atmosphere, sulfur oxides convert to sulfuric acid by reaction with moisture, and harm vegetation, aquatic, animal and human life. Consequently, ultralow sulfur diesel (ULSD) fuel sold in North America must contain less than 15 ppm sulfur, as dictated by the US Environmental Protection Agency (EPA). In Europe, the sulfur content limit is even lower, at 10 ppm, as per the European Union’s ‘Euro V’ Fuel Standard. Similar sulfur content limits are being adopted by other parts of the world to reduce air pollution and other environmental impacts.

Quantitative analysis of sulfur in crude oil, petroleum products and feedstock is extremely important to ensure compliance with regulatory bodies and legislation; failure to do so can result in costly fines. Analysis techniques for sulfur content measurement include wet chemistry, X-ray fluorescence, atomic spectroscopy and various thermal combustion methods with different detection limits. Regardless of the technique employed for measurement, robust analytical data is paramount for calibration and/ or verification. The use of high-quality CRMs certified to ISO/IEC 17025 and ISO 17034 is critical to ensuring confidence in the measurement results achieved.

Paragon scientific’s sulfur certified reference materials

Paragon Scientific’s Sulfur CRMs are suitable for calibration, verification, or for use in quality control procedures used for analyzing sulfur content in petroleum products. Our initial range includes sulfur in

  • light mineral oil
  • heavy mineral oil
  • synthetic diesel
  • kerosene (odorless)

with sulfur content ranging from 0 (Blank) through 5.0000% (50,000 ppm) for each material. More matrices are to be launched in the near future, including sulfur in isooctane and more.

Each Sulfur CRM provides traceability of measurement to recognized national standards, and to units of measurement realized at the National Physics Laboratory (NPL) or other recognized national standards laboratories. All sulfur content values are traceable to National Institute Standards and Technology (NIST), and each CRM provides low levels of uncertainty, ensuring maximum accuracy of data at hand.

Paragon also offers set sulfur kits for each matrix and the appropriate associated test methods, providing easy and efficient procurement solutions for end-users.
