Certified reference material (CRM) is an important tool in any laboratory. It offers a degree of assurance regarding the accuracy of results, as the reference material is traceable to a recognized standard. It is especially important for laboratories conducting research and development, as it allows for the confirmation of results and accurate comparison of results from different laboratories.

CRMs are typically composed of multiple substances in different concentrations. The substances are usually certified to a specific standard and may also be certified to multiple sets of standards. This allows for the comparison of results between instruments, as well as between different laboratories. The most common types of certified reference materials are traceable to the National Institute of Standards and Technology (NIST) or the American Society for Testing and Materials (ASTM).

In order to use CRMs, laboratories must adhere to the guidelines and instructions set out by the supplier. It is important to follow these instructions, as this ensures the accuracy of the results. It is also important to have a system in place for the storage and handling of the CRMs, as contaminants can affect the accuracy of the results.

CRMs are also used in laboratory quality control, as they provide a degree of assurance that the results obtained are accurate. This is particularly useful in industries such as pharmaceuticals, cosmetics, and food production, where accuracy is of the utmost importance. CRMs can also be used to validate the performance of instruments, as they offer a degree of accuracy that is not achievable with standard samples.

In conclusion, certified reference material (CRM) is an essential tool in any laboratory. It provides a level of assurance regarding the accuracy of results, as the reference material is traceable to a recognized standard. It is used in laboratory quality control, as it provides a degree of assurance that results are accurate. It is also used to validate the performance of instruments and to compare results between instruments and between different laboratories.
