Food Safety


The main tasks of metrology in food safety include developing and maintaining national standards and reference materials and providing traceability for measurements of food and agriculture products; conducting research on food-safety-related measurement science and technology. Division of Engineering Metrology and Testing Technology and Division of Chemical Metrology and Analytical Science are working on this field of metrology. The main...

  • Development of CRMs for the Monitor of Water...

    The main work is to develop CRMs which influence mouthfeel, taste of water and organic pollutant, including Microcystin–LR, Geosmin and 2-MIB. The achievement would improve and perfect the trace system of national water quality monitor, improve...

  • Research on Arsenic Speciation CRMs

    Six arsenic species certified reference material (CRM) solutions have been developed. The speciation and purity of arsenic in the CRMs were determined using NMR, HPLC-ICPMS methods. Several accurate methods with different principles were used to...

International Cooperation

  • CCQM organized eight key comparisons/pilot studies for elemental speciation from 2005. NIM organized and attended all of them, and got satisfied results. On this basis, 10 CMCs about element speciation were claimed.

National Measurement Standards and CMCs

National Primary Standard for Humidity Measurement, Dew Point Range -85℃~70℃, U=(0.1~0.4)℃,k=2

Freezing Point Depression Equipment, -190℃~+350℃, accuracy better than 0.01℃
