Area of Science:

  • Analytical Chemistry
  • Geochemistry
  • Environmental Science

Background:

  • Certified reference materials (CRMs) are crucial for accurate analytical measurements.
  • International databases facilitate access to CRMs for researchers worldwide.
  • The International Atomic Energy Agency (IAEA) manages a key CRM database.

Purpose of the Study:

  • To update and prepare the IAEA's database of certified reference materials for internet implementation.
  • To enhance user accessibility through a structured, searchable interface.
  • To provide a comprehensive resource for identifying CRMs of natural origin.

Main Methods:

  • Database compilation and update (1998).
  • Development of a user-friendly internet interface.
  • Implementation of two browsing pathways: matrix classification and producer name.
  • Data aggregation for measurands, reference materials, and producers.

Main Results:

  • The database contains over 20,000 values for 480 measurands and 1085 reference materials from 43 producers.
  • A user-friendly structure with two browsing options was successfully implemented.
  • 66% of the listed materials contain values for trace and minor elements.

Conclusions:

  • The updated IAEA database provides an accessible and valuable resource for certified reference materials of natural origin.
  • The internet implementation enhances the discoverability and utility of CRM data.
  • The database is particularly rich in materials relevant to trace and minor element analysis.
