Description
Alloy Geek 75% Sterling Silver Certified Reference Material
The 75% Sterling Silver Standard stands as an established Certified Reference Material (CRM), meticulously crafted to uphold the robust standards of silver analysis. This CRM is fashioned in adherence to the stringent regulations set forth by ISO Guides 31, 34, and 35, ensuring its international applicability and consistency for in-depth analytical endeavors. The certified chemical composition of this CRM is demarcated in weight percent, containing 75.0% Silver and 25.0% Alloy. These explicit values ensure a comprehensive and exact standard for calibration and assessment in analytical procedures related to silver and its alloys. The silver sample size is consistently maintained at approximately a 1/2 inch square, providing ample material for diverse analytical techniques, hence ensuring the reliability and repeatability of silver and alloy analyses.
| Element | Certified Reference Value (weight %) |
|---|---|
| Silver | 75.0 |
| Alloy Content | 25.0 |
Within the framework defined by ISO Guide 30, the 75% Sterling Silver Standard is classified as a Certified Reference Material, offering a robust and trustworthy reference for analytical operations across various domains and applications. The specific and verified chemical composition of this CRM ensures that analysts and laboratory professionals are empowered to conduct precise and reliable analytical evaluations. Employing the 75% Sterling Silver Standard within analytical processes markedly bolsters the accuracy and standardization of silver and alloy analysis globally, fortifying rigorous quality control and enhancing global standards in precious metal assessment.
Reference Material (RM): A reference material, or RM, is a material with a known composition or property that is used for informational purposes to look at analytical instruments, methods, or procedures. It serves as a point of comparison to ensure the accuracy and reliability of measurements. Reference materials can vary in terms of their level of characterization and traceability. Some reference materials may have well-defined properties, but they might not have undergone the rigorous testing and certification process that certified reference materials (CRMs) undergo. Reference Material chemical compositions are for information purposes.
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.
In summary, the main difference between a reference material and a certified reference material lies in the level of characterization, validation, and certification. CRMs have undergone a more comprehensive and rigorous testing process, resulting in certified values and uncertainties that can be confidently used for instrument calibration, quality control, and research. Reference materials, on the other hand, can provide a point of comparison but do not have the same level of certification and traceability as CRMs. When accuracy and traceability are critical, certified reference materials are preferred.
