CIRAM laboratories,
the benchmark for analysis and dating

In 2005, CIRAM revolutionized science for Art by defining a new approach based on high scientific standards and constructive dialogue with the markets.

Since then, numerous players in the art and heritage markets on every continent have placed their trust in us every day.

Beyond heritage, CIRAM also puts its expertise at the service of industrial players. Our certified analyses make it possible, among other things, to quantify biobased carbon, guarantee compliance with standards, and promote eco-responsible initiatives.

With over 20 years of experience and international recognition, CIRAM stands out as a trusted scientific partner for our three sectors: archaeology, art, and industry.

X-ray, infrared and UV fluorescence reveal the invisible details of works of art, such as preparatory drawings, restorations and hidden signatures.

Fields of application

CIRAM analyzes, tests, and certifies your industrial products in accordance with the NF EN 16640, ASTM D6866, NF EN ISO 21644, NF EN ISO 13833, and ISO 16620-2 standards. Every day, our laboratories:

  • Measure the biobased and petrosourced content of solids, liquids, and gases;
  • Check raw materials and validate compliance with regulations and standards;
  • Certify products to obtain an ecolabel or certification.

The CIRAM laboratories offer industrial product analysis in the following fields:

  • Biofuels, food processing, biogas and smoke, polymers, cosmetics, paints, pigments, paper, packaging, SRF.

CIRAM guarantees reliable analyses to ensure the traceability and conformity of your products.

Contact our teams

For over 20 years, CIRAM has supported museums, antique dealers, auction houses and institutions in dating and authenticating works of art through rigorous scientific analysis.

Dating all materials

All works of art can be dated and analyzed. Our laboratories analyze a wide range of materials using state-of-the-art analytical techniques:

  • Carbon 14: wood, ivory, paper, textiles ;
  • Thermoluminescence: terracotta, porcelain, ceramics ;
  • Scanning electron microscopy: stone, bronze, iron, silver, gold, glass, pigments ;
  • X-ray fluorescence: stone, bronze, iron, silver, gold, glass, enamel, pigments ;
  • Infrared spectrometry and GC-MS: all organic materials (binders, resins, glues, etc.).

These methods can be combined for more precise dating.

Analysis of the tables

The authentication and study of pictorial works requires advanced imaging techniques:

  • Grazing light and ultraviolet imaging: varnish conservation, observation of restorations and repaints;
  • X-ray radiography: identification of areas of restoration and general state of conservation of the painting;
  • Infrared reflectography: revealing preparatory drawings, repentirs and hidden signatures.

CIRAM combines expertise and innovation to guarantee reliable analyses tailored to the art market.

Contact our teams

CIRAM supports archaeologists by performing laboratory and on-site analyses.

To meet all your archaeological needs and constraints, our laboratory scientists offer a range of dating and analysis techniques:

  • Carbon-14 dating: measurement of isotopes 12, 13, and 14 to date all types of organic materials.
  • Isotopic analyses: study of stable isotopes of carbon, nitrogen, strontium, and sulfur to reconstruct diets and population movements.
  • Analysis of organic residues: identification of traces of food and drink on artifacts.
  • Scientific imaging: X-ray radiography and 3D tomography for virtual excavations.
  • Anthracology and xylology: identification of wood species, on wood and charcoal.

By combining these methods, CIRAM guarantees precise analyses tailored to archaeological problems.

Are you asking yourself these questions?

What is carbon-14 dating and how does it work?

Carbon-14 dating is a scientific method used to determine the age of organic materials by measuring the amount of carbon-14 they contain.

What types of materials can I have analyzed by CIRAM?

CIRAM analyzes a wide range of materials, including wood, paper, ceramics, glass, precious metals (silver, gold), as well as stones and paints.

How does CIRAM ensure the accuracy of its analyses?

CIRAM uses proven methods and state-of-the-art equipment to guarantee accurate results. Our scientists combine several dating and analysis techniques to increase the reliability of results, taking into account the specificities of each material.

How long does a CIRAM laboratory analysis take?

Timescales vary according to the complexity of the analysis and the type of material to be analyzed. We strive to deliver accurate results as quickly as possible, while maintaining the necessary scientific rigor.

How can I contact CIRAM for a project?
