Conostan Reference Materials
CONOSTAN® is the most recognized and trusted name in oil standards.
Beginning more than 40 years ago, the uniquely superior CONOSTAN® product chemistry and proprietary blending techniques set a higher standard for the quality and stability of oil reference materials. This technology was born out of Petroleum industry partnerships and investment, making it ideally suited to meet the needs of key application areas like wear metals analysis, sulfur analysis, lubricant manufacturing, and petrochemical process monitoring.
TAN
The titration curves for every concentration of the CONOSTAN family of TAN standards has more prominent inflection points and a wider difference between the starting ph and final pH during titration, in comparison with other suppliers.
TBN
Each CONOSTAN TBN standard is formulated to provide a strong levering influence on the titration curve creating dramatic and easy to determine inflection points. Concentration uncertainties for TBN are less than 1%.
S-21 Organometallic Standards
Conostan metallo-organic standards are oil-based metal calibration standards for use with ICP, AA, rotrode, XRF, DCP, flame emission and other instruments.
S-12 Organometallic Standards
The chlorine product line is designed for calibration of XRF, ICP, and analytical techniques. Stocked concentrations are shown in the table below. Other concentrations are available as custom blends.
Chlorine in Oil
The chlorine product line is designed for calibration of XRF, ICP, and analytical techniques. Stocked concentrations are shown in the table below. Other concentrations are available as custom blends.
Flash Point Standards
Flash Point Standards are used to verify laboratory flash point instruments that are used to test petroleum products. These standards are for use in accordance with ASTM D93, ISO 2719 & IP 34. Complete with a detailed Certificate of Analysis.
