Description
Alloy Geek Car Catalyst 20 Certified Reference Material
The Car Catalyst 20 sample is a high-quality Certified Reference Material (CRM) diligently prepared in compliance with the rigorous standards delineated in ISO Guides 31, 34, and 35. These internationally recognized standards guarantee the reliability, accuracy, and consistency of the CRM, which is crucial for ensuring the validity of analytical measurements in the assessment of car catalysts. Specifically designed for the calibration of instrumentation and the validation of analytical techniques, the Car Catalyst 20 sample helps to establish the accuracy and precision of measurements pertaining to car catalysts' chemical composition, including the elements lead, palladium, platinum, and rhodium.
| Element | Certified Reference Value (ppm) |
|---|---|
| Lead | 6228 |
| Palladium | 326 |
| Platinum | 697 |
| Rhodium | 51 |
Adhering to the definition set forth by ISO Guide 30, the Car Catalyst 20 sample qualifies as a Certified Reference Material. This CRM is characterized by its certified chemical composition: 6228 ppm Lead, 326 ppm Palladium, 697 ppm Platinum, and 51 ppm Rhodium. These certified reference values are meticulously determined to offer optimal accuracy and reliability in calibration and analytical method validation. Utilization of the Car Catalyst 20 sample in analytical methodologies ensures stringent quality control and promotes the attainment of consistent and dependable results in the examination and analysis of car catalysts.
It is necessary to use proper testing procedures when testing this CRM. This includes a requirement for sample cups and film for XRF 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.
