Description
Alloy Geek Car Catalyst 10 Certified Reference Material
The Car Catalyst 10 sample, a Certified Reference Material (CRM), is meticulously prepared following the stringent guidelines as specified by ISO Guides 31, 34, and 35. These guidelines ensure the precision and accuracy in the measurement and consistency in the production of the CRM. This CRM is intended for the calibration of analytical equipment and the validation of analytical methods used in assessing the chemical composition of car catalysts. Ensuring the reliability and accuracy of measurements, the Car Catalyst 10 sample provides confidence in the analysis of car catalyst samples, particularly for palladium, platinum, and rhodium.
| Element | Certified Reference Value (ppm) |
|---|---|
| Palladium (Pd) | 1075 |
| Platinum (Pt) | 465 |
| Rhodium (Rh) | 242 |
In adherence to the definition as provided in ISO Guide 30, the Car Catalyst 10 sample stands as a Certified Reference Material. Its certified chemical composition is 1075 ppm for Palladium, 465 ppm for Platinum, and 242 ppm for Rhodium. These values are carefully ascertained to ensure the utmost accuracy and reliability in calibration and method validation. Utilizing the Car Catalyst 10 sample in analytical processes guarantees stringent quality control, supporting laboratories in achieving consistent and reliable results in the 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.
