To improve the performance of your materials and nanomaterials, LNE offers a complete range of services and has test and measurement platforms adapted to their characterization and analysis. LNE also designs reference materials to make your measurements more reliable.
Why characterize your materials?
Whether you work in the construction, cosmetics, nuclear, medical, packaging or industrial sectors, where the quality requirements are high, the services offered by LNE allow you to:
- To ensure the reliability of the characteristics of your materials and the robustness of their properties,
- Optimize the performance of your materials,
- Adapt and improve them to meet technological or environmental requirements,
- Choose them wisely according to their use,
- Control the risk of failure, both during the design and during the use of the final product.
Expertise in material characterization and analysis of their properties
Using its multi-technical platform, LNE can analyze the chemical, physical, mechanical, and structural properties of your materials, down to the nanometer scale, through chemical, physical, and mechanical testing.
Its expertise is based on its ability to formulate hypotheses for the qualification of your material in relation to the expected analysis objective: performance improvement, failure study, etc.
Thanks to personalized technical support, LNE positions itself as your single point of contact, capable of taking charge of your project as a whole and helping you achieve your objectives.
The characterization proposed by LNE consists of analyzing your material to evaluate and optimize its performance, as well as its evolution over time. He can adapt these methods to your needs and assess the compliance of the material with regard to the standards in force or your specifications.
- Thermal properties : conductivity and thermal resistance, emissivity, infrared thermography, in-situ measurements, large-scale tests, etc.
- Mechanical properties : tensile behaviour, compression, shear, bending, fatigue, punching, creep, characteristics and dimensional stability, loose insulation settlement, etc.
- Electrical and magnetic properties: measurement of resistivity/conductivity, permeability, etc.
- Hygrometric properties: permeance / permeability to water vapour or liquid water, moisture content, sorption and desorption
- Physico-chemical properties : chemical composition, gas content, microscopic analyses ...
- Optical properties : measurement and technical expertise on the optical performance of your materials, photosensitivity, etc.
- Acoustic properties : measurement of aS and aW coefficients in accordance with international and French standards, classification of sound absorbers, etc.
- Reaction to fire tests : regulatory compliance tests, assessment of risks of degradation, ignition and propagation, analysis of effluents, etc.
- Environmental testing: climatic, ECM, electrical safety, vibrations, transport simulations.
Focus on nanomaterials
LNE has specific expertise in the properties of nanomaterials and nanoparticles. His expertise covers the characterization of physicochemical properties in multiple media, the evaluation of exposure to nano-objects at different stages of a product's life, and the evaluation of their performance.
Among the services offered:
- Particle size distribution and chemical composition, powder powder powder measurement, specific surface area characterization,
- Physico-chemical characterization of aerosols,
- Characterization of powders, materials and finished parts.

In terms of applications, we can meet your needs for:
- Measurement of volatile organic compounds (VOCs),
- Specific material analysis and metallographic analyses,,
- Study of the coating and test and analysis of the resistance of a material,
- Analysis of the structural evolution of the metal, UV aging and characterization,
- Tensile on notched specimens followed by fatigue and static load tests,
- Etc.
Conformity assessment:Our experience in standards and regulations also allows us to assess the conformity of your products and to support you in their evolution or in the development of your new materials.
Analyzing material properties allows you to control the risk of failure, both during design and during the use of the final product. In the event of a proven failure, LNE has a microscopic platform to study: loss of performance, deterioration (crack, erosion, porosity, corrosion, etc.), breakage and premature degradation of parts, identification of a deposit or pollution, etc.
