The 10K Gold Standard is a superior Certified Reference Material (CRM), meticulously designed to enhance the precision and reliability of gold analysis. In adherence to the stringent standards set by ISO Guides 31, 34, and 35, this CRM guarantees international compatibility and trustworthiness for exhaustive gold assessments. The 10K Gold Standard holds a certified chemical composition articulated in weight percent, consisting of 41.78% Gold, 9.66% Silver, 39.67% Copper, and 8.89% Zinc. This diverse elemental composition offers a reliable and precise standard for analytical assessments and calibrations. Each 10K Gold Standard sample is thoughtfully prepared at an approximate size of a 1/2 inch square, ensuring ample material for diverse analytical processes and confirming the reliability and repeatability of gold analyses.
| Element | Certified Reference Value (weight %) |
|---|---|
| Gold | 41.78 |
| Silver | 9.66 |
| Copper | 39.67 |
| Zinc | 8.89 |
As defined by ISO Guide 30, the 10K Gold Standard stands as an esteemed Certified Reference Material. It is a robust benchmark for gold analysis across various analytical disciplines. Its rigorously confirmed chemical composition allows analysts and laboratory professionals to conduct their assessments with the highest degree of accuracy and confidence. The use of the 10K Gold Standard in analytical evaluations plays a critical role in ensuring the continuity and uniformity of gold analysis globally, underscoring stringent quality control and bolstering international standards in the realm of precious metal analysis.
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.
