Canadian Reference Materials (CRM) are certified reference materials of high-quality and reliability produced by the National Metrology Institute of Canada – the National Research Council Canada. The NRC Certified Reference Materials program is operated by the Measurement Science and Standards portfolio and provides CRMs for environmental, biotoxin, food, nutritional supplement, and stable isotope analysis. The program was established in 1976 to produce CRMs for inorganic and organic marine environmental analysis and remains internationally recognized producer of CRMs. ==Inorganic CRMs== NRC produces certified reference materials of biological tissues, isotopic standards, natural waters, sediments, supplements, and natural health products. With the exception of the ORMS, the river water CRM with elevated mercury, all materials contain natural levels of analytes in their native matrix. * Biological tissues * * DOLT, dogfish liver for trace metals * * DORM, fish protein for trace metals * * LUTS, non-defatted lobster hepatopancreas for trace metals * * TORT, lobster hepatopancreas for trace metals * Isotopic materials * * NIMS, natural inorganic mercury standard * * EMMS, isotopic methylmercury standard * Natural waters * * CASS, near-shore seawater for trace metals * * MOOS, seawater for nutrients * * NASS, seawater for trace metals * * ORMS, river water for mercury * * SLEW, estuarine water for trace metals * * SLRS, river water for trace metals * Sediments * * HISS and MESS, marine sediment for trace metals and major constituents * * PACS and SOPH, marine sediment for trace metals and major constituents * Supplements and natural health products * * CACB, calcium carbonate for lead and cadmium * * FEBS, otolith for trace metals * * SELM, selenium-enriched yeast for selenium 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Canadian Reference Materials」の詳細全文を読む スポンサード リンク
