Description
10 Piece Set of Alloy Geek SMO 01-10 - Sulfur in Mineral Oil Certified Reference Materials
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.
| Standard | Certified Sulfur Value (weight %) | Uncertainty (weight %) |
|---|---|---|
| SMO 01 | 0.0000 | 0.00000 |
| SMO 02 | 0.1001 | 0.00100 |
| SMO 03 | 0.2000 | 0.00200 |
| SMO 04 | 0.5000 | 0.00500 |
| SMO 05 | 0.7502 | 0.00750 |
| SMO 06 | 1.0000 | 0.01000 |
| SMO 07 | 2.0001 | 0.02000 |
| SMO 08 | 3.0000 | 0.03000 |
| SMO 09 | 4.0001 | 0.04000 |
| SMO 10 | 5.0002 | 0.05000 |
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.
Certified Reference Material (CRM): A certified reference material, or CRM, is a type of reference material that has been thoroughly analyzed and characterized using multiple validated methods to determine its composition or properties. The results of these analyses are then used to establish certified values, along with associated uncertainties. CRMs are produced and certified by accredited organizations or laboratories following internationally recognized standards, such as ISO Guide 34 (ISO 17034). The certification process includes interlaboratory comparison and statistical analysis to ensure accuracy and traceability.
