HOME > National Metrology Institute of Japan
As the national metrology institute (NMI), we are focusing on the development and dissemination of measurement standards, promotion of measurement standards utilization, development of measurement technologies related to measurement standards, legal metrology work and training of experts. Our activity covers engineering, physical, material, and chemical measurement standards. It also covers development of measurement and analytical instrumentation. We also coordinate international activities on metrology standards as a national representative.
Using quantitative nuclear magnetic resonance spectroscopy and other methods, AIST has developed two types of certified reference materials (standard solutions) composed of target substances for doping testing. The reference materials will contribute to higher reliability of doping testing at international sports events.
The role of certified reference materials in doping testing
AIST developed a surface profiler for planar substrates. The profiler directly measures the surface profile without the need for a reference plane, and can measure the profile of planar substrates with a diameter of up to 600 mm to an absolute accuracy of 5 nm or less.
