Fossil wood samples dated by the CIRAM laboratory
The CIRAM has dated two fossil woods whose exceptional preservation is explained in particular by their burial in a humid, oxygen-poor environment.

Accredited laboratory ISO-IEC 17025*, CIRAM supports guarantees reliable isotopic analyses for industry.

ISO-IEC 17025 accreditation*, issued by COFRAC, is the international benchmark for testing and calibration laboratories. It attests to their technical competence, the validity of their methods, and the reliability of their results. Unlike method standards that define how to measure a parameter, ISO-IEC 17025 certifies that the laboratory itself is capable of performing its analyses under strictly controlled, auditable, and reproducible conditions.
In Martillac, near Bordeaux, CIRAM is accredited ISO/IEC 17025* for the stable isotopic analysis of carbon and nitrogen and the graphitization of organic materials. This site, unique in France, was designed to accommodate sensitive and complex analyses in a secure scientific environment. This official recognition reflects our daily commitment: to provide our clients with reliable, reproducible, and trustworthy results.
