The SMO 01 through SMO 10 Standards constitute a comprehensive set of Certified Reference Materials (CRMs) explicitly designed for the precise calibration and validation of sulfur analysis in mineral oil. Manufactured in strict accordance with ISO Guides 31, 34, and 35, each standard in the series represents varying sulfur content levels, ranging from 0.0000% to 5.0002% (weight percent), ensuring a broad spectrum of reference points for accurate analysis. The CRMs are packaged in amber bottles, safeguarding the mineral oil matrix from light exposure and subsequent degradation, thereby maintaining consistent quality and reliability.

In alignment with ISO Guide 30, the SMO series is validated as CRMs, ensuring their reliability and precision for sulfur in mineral oil analysis. The accompanying Certificate of Analysis for each standard in the SMO series provides explicit details, including certified sulfur values and the corresponding uncertainties, which increase with sulfur content. This exhaustive set of CRMs assists laboratories in achieving consistent, trustworthy, and precise analytical results, bolstering the assurance in analytical findings across diverse research and industrial settings.
