Certified Reference Material

BCR ERM® Chemical Standards

As part of our partnership with the IRMM (Institute for Reference Materials and Measurements), Sigma-Aldrich is pleased to offer the European Reference Materials (ERM) line of premier chemical standards.

ERM is a new benchmark in high-quality standard reference materials that ensures reliability and comparability of the results of chemical analysis. ERM products are certified and undergo uncompromising peer evaluation.

The key features of ERM products and their benefits to the analyst are:

  • Full transparency of the certification principles and the evaluation report provides valuable insight to help analysts get the maximum benefit from the use of the material.
  • Traceability clearly stated and defined ensures applicability of the materials to the respective analytical application.
  • Internationally recognized values underpinned through the participation of the producing institutes in the key comparisons organized by the Bureau International des Poids et Mesures.

The full range of ERM products covers the key analytical sectors. A few examples include:

  • Environmental, standards for sulfur in fuel
  • Food, standards for dietary fiber
  • Clinical, certified thromboplastin standards

Present partners of the ERM concept are:
