Certified Reference Materials (CRMs)
Reference material (RM) is a substance or material that has been determined to have one or more sufficiently uniform characteristic values. As a measuring tool in the industry of analysis and measurement, reference material (RM) plays an indispensable role in calibrating measuring instruments, evaluating measurement and analysis methods, measuring material characteristic values, assessing the operational technical level of analysts, quality control and other fields. Certified reference material (CRM) is a special category of reference material (RM), which must be attached with a certificate that meets certain requirements.
In addition, when a certified reference material (CRM) is combined with a specially designed device, the device may also be considered as a certified reference material (CRM). The certified reference material (CRM) may be a highly pure chemical reagent, or a mixture prepared in proportion, such as a standard pH solution, or a standard sample with complex components prepared by a certain method from a number of natural samples, such as a standard substance for clinical analysis and samples of different qualities in industry.
Application fields
Calibration instruments: The accuracy of analytical instruments plays an important role in the field of analysis, and using certified reference materials (CRMs) to calibrate instruments is the key step to obtain high accuracy.
Making standard curves: Certified reference materials (CRMs) can be used as working standards to make standard curves. Most instrumental analysis take advantages of the working curves to establish the linear relationship between the physical quantity and the concentration of measured components. If the certified reference materials (CRMs) are used to make standard curves, not only can the analysis results be established on the same basis, but also can improve the work efficiency.
Others: Certified reference materials (CRMs) can be used to evaluate the accuracy of analytical methods. Furthermore, certified reference materials (CRMs) can be applied as quality control standard sample. If the analysis result of the certified reference materials (CRMs) is consistent with the standard value, it indicates that the analytical determination process is under quality control, thus indicating that the determination result of the unknown sample is reliable.
