The NRC CRM program was originally established in 1976 to produce certified reference materials for inorganic and organic marine environmental analysis. The NRC is now an internationally recognized producer of high-quality CRMs with materials now available for analytes such as:

Algal and cyanobacterial toxins
Amino acids
Contaminants
Dietary supplements
Ethanol
Mycotoxins
Particle size
Peptides
Proteins
Stable isotopes standards
Total element content
Trace element species
Veterinary drugs
