Fossil wood samples dated by the CIRAM laboratory
CIRAM has dated two fossilized pieces of wood, whose exceptional state of preservation is due in part to the fact that they were buried in a humid, oxygen-poor environment.

CIRAM , an ISO-IEC 17025* accredited laboratory , guarantees reliable isotopic analyses for industry.

ISO/IEC 17025* accreditation, issued by COFRAC, is the international standard 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, which 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 ISO/IEC 17025* accredited for stable isotopic analysis of carbon and nitrogen, and graphitization of organic materials.) This site, the only one of its kind in France, was designed to accommodate sensitive and complex analyses in a secure scientific environment. This official recognition reflects our daily commitment to providing our customers with reliable, reproducible results that can be used with complete confidence.
