National Metrology Institute of Japan (NMIJ)

NMIJ Reference Materials

NMIJ produces certified reference materials (NMIJ CRMs) to determine measurement values in chemical measurements such as calibration of analytical instruments and evaluation of analytical procedures.
NMIJ CRMs play a hidden but indispensable role in various aspects of our lives.
They are necessary not only for industrial technology, and research and development, but also for smooth commercial activities, global environment preservation, and our health and safety.
NMIJ supplies them not only to those in Japan but also to those in the Asian region and others around the world.
