Certified Reference Materials (CRM)

Certified Reference Materials (CRMs) are highly pure substances or materials with known quantities of specific components, used to ensure the accuracy and reliability of measurements in laboratories. They serve as benchmarks for calibration and validation of testing methods, helping scientists and technicians confirm that their instruments are working correctly. By using CRMs, laboratories can produce consistent and trustworthy results, which is crucial in fields like pharmaceuticals, environmental testing, and food safety. Essentially, CRMs provide a standard for comparison, ensuring that measurements are accurate and precise.
