Introducing Sulfur Certified Reference Materials
Paragon Scientific can now manufacture premium level, dual accredited Certified
Reference Materials (CRMs) for Sulfur analysis, certified in strict accordance with
both ISO/IEC 17025 and ISO/IEC 17034 as per their accreditation to the United
Kingdom Accreditation Service (UKAS).
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 analysing sulfur content in petroleum products. Our opening range includes sulfur in
light mineral oil, heavy mineral oil, and in synthetic diesel, with sulfur content ranging from 0 (Blank) through to 5.0000 % (50000 ppm) for each material. More matrices are to be launched in the near future, including
sulfur in kerosene, iso-octane and more.
Each Sulfur CRM provides traceability of measurement to recognised national standards, and to units of measurement realised at the National Physics Laboratory (NPL) or other recognised 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 Scientific’s Sulfur CRMs are available in 100 mL volume glass containers with tamper-evident packaging, providing assurance of sample integrity. Paragon also offers set sulfur kits for each matrix and
the appropriate test methods associated, providing easy and efficient procurement solutions for end-users.

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 road 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. The sulfur content limit in
Europe is even lower, at 10 ppm. 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, calibration and / or verification. The use of high quality CRMs certified to ISO 17025 and ISO 17034 is critical to ensuring confidence of the
measurement results achieved.

Accreditation
Our viscosity standards, viscometer calibration, density standards and sucrose RI standards are all covered by our United Kingdom Accreditation Service (UKAS) accreditation to the International Standard BS/EN/ISO/IEC 17025 - 2005, in addition to this our Refractive Index standards are manufactured conforming to ICUMSA (1974). For more information about UKAS and to view our scope of accreditation (Calibration Laboratory number 0649) please visit www.ukas.org/calibration
What is ISO 17025?
ISO 17025 is a recognised international standard that specifies the requirements for the competence to carry out testing and or calibrations to a standard dictated by international methods. The international standard requires that an accredited facility comply with all the requirements detailed within the varied sections of the standard. These sections range from assuring the quality of test and calibration results to accommodation, environmental conditions, and purchasing. ISO17025 is applicable to laboratories that operate in a multitude of business sectors, some of which include automotive, cosmetics, micro-electronics, petro-chemical, pharmaceutical and power generation.
What is ISO Guide 34?
ISO Guide 34 provides the highest level of Quality Assurance, confirming the expertise of the manufacturer, the integrity of the production systems and the reliability of the Certified Reference Materials that it produces.
