Environmental Reference Materials
NIES CRMs
The National Institute for Environmental Studies (NIES) developed "Pepperbush" as Japan's first Certified Reference Material (CRM) in 1979. Since then, we have been developing environmental reference materials useful for environmental monitoring.
Environmental CRMs are utilized to evaluate new analytical methods and to control the accuracy of pretreatment and instrumental analyses.
Based on the opinions of researchers and the needs of society, the NIES produces CRMs and Reference Materials (RMs).
