The CONOSTAN® Division of SCP SCIENCE is the world's leading manufacturer and marketer of Elements in Oil standards and related spectroscopy products. CONOSTAN®`s industry leading position is derived from superior product chemistry, manufacturing technology, and blending techniques. Conostan products are used extensively in the calibration and operation of analytical instruments for the analysis of elements in oil and other organic fluids.

CONOSTAN® is the only source of metallo-organic standards in the history of the National Institute of Standards & Technology (NIST). Click here to see a history of CONOSTAN® and NIST. The variety of products afford convenience as reference and routine analytical materials for AA, ICP, DCP, XRF, Rotrode, and other analytical techniques.

Our reputation traces back to over 30 years ago, when the U.S. Department of Defense's Spectrometric Oil Analysis Program Standards Committee needed standards to analyze metals in lubricating oils and conduct wear-metals-analysis programs. At the time, commercially available metals-in-oil standards were unreliable and made calibrating analytical instrumentation difficult. The CONOSTAN® research and development department discovered and developed the chemistry for producing reliable element-in-oil standards, which were adopted by the Department of Defense.

In September 2007, ConocoPhillips and SCP SCIENCE signed a purchase-sale agreement whereby SCP SCIENCE would acquire the complete assets of CONOSTAN® from ConocoPhillips Specialty Products Division. The complete CONOSTAN® business − production, quality control, inventory, customer records − is now located at the SCP SCIENCE manufacturing facility in Baie-D’Urfé, a suburb of Montreal, Quebec, Canada.

CONOSTAN® customers can now avail themselves of the opportunity for savings by purchasing their CONOSTAN® oil-based standards together with sample preparation and analytical instruments (graphite blocks and closed vessel microwave digestion systems), supplies (torches, spray chambers and nebulizers) and aqueous standards, for atomic absorption, ICP, XRF and rotrode spectroscopy, from a single source.

WHY CONOSTAN®
CONOSTAN® oil analysis standards are optimized for:

• Compatability- 38 elements can be combined over an extensive concentration range
• Solubility - CONOSTAN® element standards are soluble in CONOSTAN® PremiSolv™ ICP solvent, Conostan base oils, Ketones, such as 4-methyl-2-pentanone (MIBK), as well as in paraffinic and aromatic hydrocarbons, such as mineral oil, xylene and Kerosene.
• Volatility - CONOSTAN® element standards are made in ultra-pure, highly processed hydrocarbon oil only; no solubilizers are used. Volatile loss depends on the volatility of the hydrocarbon oil and is typically 0.07% in one hour at 120°C and 75mm Hg pressure.
• Viscosity - Viscosity range at room temperature is ideal for instrumental applications.
• Instrumental Response - Excellent analytical response over a wide range of analytical applications.
• Shelf Life - All CONOSTAN® element standards and spectroscopy products have a one year minimum shelf life (D-Series® D-12 and D-3 blended standards have a 30 month shelf life) from the date of shipment.
