IAEA internet database of natural matrix reference materials

Abstract

The International Atomic Energy Agency maintains a database on internationally available certified reference materials of natural origin. The database was updated in 1998 and prepared for an Internet implementation. A user-friendly structure was created, providing two main pathways for browsing, either according to the matrix classification or the producer's name. The database presently contains over 20,000 values for 480 measurands and 1085 reference materials from 43 different producers. Most of the materials entered contain values for trace and minor elements (66%).

The natural matrix reference material database of the International Atomic Energy Agency: Reference materials in support of dietary investigations

“…The structure of the database as it developed over time until it was put on the Internet is described elsewhere (Bleise et al, 1999Iyengar and Bleise, 2001).…”

Analytical Chemistry of Element Determination (Non‐Nuclear and Nuclear)

“…The latter contains multiple tables of biological and environmentally related RMs for trace elements, radionuclides, stable isotopes and microcontaminants, including producers, RMs sorted by manufacturer and RMs sorted by element and by increasing concentrations. Bleise et al (2001) discuss the updated IAEA database of natural matrix RMs as an almost comprehensive compilation of available biological and environmental reference materials of natural origin (human and animal tissues, foods, plants, soils, sediments, etc.) for trace elements, radionuclides, stable isotopes and organic contaminants.…”

Rare Earth and Other Trace Element Content of NRCC HISS‐1 Sandy Marine Sediment Reference Material

“…Continuous participation in these exercises has helped monitor the performance of our laboratory and the quality of our analytical data (Coquery et al 1999, Okamoto et al 1999). For quality assurance (QA) purposes, trace element content is used to select a suitable reference material (RM) to serve as a calibrator that closely matches the sample to be analysed (Bleise et al 2001). Certified reference materials (CRMs) play a prominent role in setting quality standards in laboratories through the validation of analytical methods, the detection of discrepancies in methodologies and the assessment of the quality of laboratory performance (Povinec 1996).…”
