What are certified reference materials?

Certified reference materials (CRM) are sample materials of known composition and other properties that can be used for calibration, quality control and related activities. In many registry regions for standards, they regulate that can produce certified reference materials and distinguish between them and materials without certificates allowing only devices that meet specific standards to issue certificates. The certificate suggests that the products have been produced or processed in a fixed device and meet legal standards for use as reference materials. This material must meet very accurate purity and quality standards; For example, in the calibration of the mass spectrometer, the researcher needs a known material to be used in the test. Certified reference materials can be held at hand for calibration, quality control and point checks to confirm that the device is working properly. Scientists can also compare reference materialy with unknown samples to find out how they coincide. Prices may vary depending on the material and access to some materials is limited for safety reasons. Toxic or potentially hazardous materials are usually available only through a limited number of resources and these organizations are cautious, which products release and to whom. For example, nuclear reference materials are solved with extreme care, as well as certain biological samples.

These materials may include pure reference samples and compounds and solutions, some of which can be diluted at different levels. If the certified reference material is required for a very specific purpose, the manufacturer of the CPSOUT specifications and to provide an estimate of the costs and delivery time. For complicated tasks, the costs may increase significantly, especially if the customer wants to give a rush to a particular project or need.

ofCeards keep certified reference materials in a safe environment to reduce the risk of contamination and other problems. Access can be limited to specific staff who may have to sign materials in the protocol and take responsibility for their safety and security when they are not out of storage. Confidential and secure materials are often limited to use in the premises and staff cannot take them to distant sites or other devices without explicit permission.
