To improve the performance of your materials and nanomaterials, LNE offers a comprehensive range of services and has testing and measurement platforms adapted to their characterisation and analysis. LNE also designs reference materials to ensure the reliability of your measurements.
Why characterise your materials?
Whether you work in construction, cosmetics, nuclear, medical, packaging or industry – where quality requirements are high – the services offered by LNE allow you to:
- Ensure the reliability of your materials’ characteristics and the robustness of their properties,
- Optimise the performance of your materials,
- Adapt and improve them to meet technological or environmental requirements,
- Select them appropriately according to their use,
- Manage failure risks, both during design and in the final product's usage.
Expertise in characterisation and property analysis
Using its multi-technique platform, LNE can analyse the chemical, physical, mechanical and structural properties of your materials, down to the nanometre scale, through chemical, physical and mechanical testing.
Its expertise lies in its ability to formulate qualification hypotheses for your material, based on the intended analysis objective: performance improvement, failure investigation, etc.
Thanks to personalised technical support, LNE acts as your single point of contact, able to manage your project as a whole and help you achieve your objectives.
LNE's characterisation services aim to analyse your material in order to evaluate and optimise its performance and monitor its behaviour over time. Methods can be adapted to your needs and used to assess the material’s compliance with current standards or your technical specifications.
Our technical teams also assist in conducting custom tests to manage failure risks and optimise the performance of materials used in your manufacturing processes.

Focus on Nanomaterials
LNE has specific expertise in nanomaterials and nanoparticles. This includes the characterisation of physicochemical properties in various environments, assessment of exposure to nano-objects throughout a product’s lifecycle, and performance evaluation.
Services offered include:
- Particle size distribution and chemical composition, dustiness measurement, specific surface characterisation,
- Physicochemical characterisation of aerosols,
- Characterisation of powders, materials and finished parts.
Discover all the services for nanomaterials (in French)
We can meet your needs for:
- Measurement of Volatile Organic Compounds (VOCs),
- Specific material analysis and metallographic studies,
- Coating study, resistance testing and analysis,
- Structural evolution analysis of metals, UV ageing and characterisation,
- Notched specimen tensile testing followed by fatigue and static load testing,
- Etc.
Compliance evaluation: Our knowledge of standards and regulations also allows us to assess your product’s compliance and support you in its development or the creation of new materials.
Analysing material properties helps you manage the risk of failure during both the design and usage phases of the final product. In the event of proven failure, LNE has a microscopy platform to study: performance loss, degradation (cracks, erosion, porosity, corrosion, etc.), rupture, premature part failure, deposit or contamination identification, etc.
>>Failure diagnosis and expertise (in French only)
In relation to materials’ service life, LNE supports you in interpreting results and understanding changes in the original properties of your product.
>>Service life of materials and systems (in French only)
Our experts can also support recyclability and reuse studies by characterising the critical performance of stored materials, in compliance with applicable standards.
LNE has specific expertise in contact materials and packaging, and can carry out health and safety measurements on food packaging (including cellulosic/bio-sourced and recycled products) and materials in contact with food, cosmetics and medicines.
Example services:
- Permeability of materials, packaging and industrial products,
- Health safety of materials and packaging in contact, migration testing,
- Validation of medical device packaging,
- Transport simulation,
- Food contact compliance.
>> Developing high-performance packaging and/or meeting food contact regulatory requirements
