Sulfur standards

Sulfur level is regulated in many fuel oils and is directly related to fuel quality. ASTM, ISO, EPA, and other industry standards for the determination of sulfur concentration in petroleum fuels specify the use of matrix-matched calibration standards to ensure the accuracy and reproducibility of results. CONOSTAN® sulfur CRMs provide the accuracy and precision you need when testing according to ASTM D2622, D4294, D5453, or other common methods.

With ready-to-use sulfur concentrations from 0.5 to 60000 ppm and an extensive range of matrices including Mineral Oil, Diesel, Residual Oil, Isooctane, Biodiesel, and Crude oil, this family of standards can help you achieve the highest possible integrity in your sulfur analysis data.

Chlorine standards

Our chlorine standards line is designed for use during the calibration of XRF, ICP, and similar comparative analytical techniques. The CONOSTAN catalog includes concentrations from 10 to 50000 ppm in 75 cSt mineral oil to cover a range of common uses.

Do you have a unique requirement? This product line can be customized to suit your specific concentration requirements or for combined sulfur and chlorine standards.
