With the scientific support of our network of researchers in Burgundy, our team supports you with your R&D projects and/or carries out analyses, expert assessments and studies according to your needs.


Our analyses allow the characterization of materials and compounds in massive, powder, porous, solution and gaseous forms. Our panel of equipment enables:

  • raw materials to be tested for compliance in terms of physical, chemical, thermal or mechanical properties
  • impurities to be searched and identified in localized form or in a matrix
  • anomalies in material behavior to be highlighted

Expert assessments

In order to carry out expert assessments, the scientific training and the experience of our teams are a real asset. Expert assessments implement different angles of investigation associated with complementary characterization techniques. The services commonly provided are:

  • failure or behavior expert assessments
  • corrosion expert assessments
  • advanced deformation of materials


Sayens is located in the heart of the Physics and Chemistry laboratories of the University of Burgundy. This environment and the permanent exchanges with the research world allow us to support you with your development projects. We offer the following services:

  • defining specifications for research actions coupled with experimentation and bibliography for the qualification of processes,
  • interpreting complex chemical reactions,
  • carrying out advanced studies of corrosion and proposing protection solutions, optimizing material performances…
  • developing innovative physicochemical techniques in connection with research laboratories for advanced characterization

What type of materials do you want to analyze? 

We analyze, appraise and carry out scientific studies in the major fields of materials classification. This list is not exhaustive as we also regularly make “excursions” into the world of active ingredients and pharmaceutical materials as well as into the plant or biological field. Material characterization is multi-faceted and its aim remains to explain the behavioral phenomena.

Thermal analyzers can determine the physical properties of materials depending on the temperature: chemical decomposition, melting, change of phase or state …
The analyzed properties are an integral part of the material’s identity and allow, in addition to the verification of characteristics, “diverted” chemical information to be obtained within the framework of compound identification.

Thermogravimetric analysis (TGA) | DSC analysis | Dilatometry | Thermal diffusivity

The physical and mechanical properties are a direct result of the materials’ composition, their shaping and the treatments they undergo. They make it possible to check the compliance of materials, to determine the characteristics necessary to predict their implementation and to understand the cause of failures. These characterizations concern, according to the quantity to be measured, polymers or alloys, but also pasty or viscous samples.

Rheometry | Capillary Rheometry | Viscosity | HDT Vicat Viscosity | PVT Viscosity | Viscosity Fluidimetry | Viscosity index | Mechanical tests | Residual stress measurement | Mechanics, Endurance and Vibration | Acoustic Testing and Imaging

Our elemental and structural chemical analysis techniques allow materials and compounds to be identified.
We can identify a metal grade, a polymer family, mineral compounds, identify the nature of pollutants, etc.
We cover the fields of identification from trace analysis to major elements, in various matrices, in aggregate form or in a very localized way.

X-ray diffraction (XRD) | X-ray fluorescence – EDX microprobes | Infrared spectrometry (FTIR) | Water content (Karl Fisher)

The direct observation of materials at different scales, under different radiations, which can be coupled to a chemical or physical analysis, makes it possible to obtain very complete information on the state of the material and its intrinsic characteristics.

Electron microscopy (SEM/EDX, TEM) | Optical microscopy | Local probes (AFM, SMM, Nano IR)

The characterization of the extreme surface, physical or chemical on a few nanometers, makes it possible to identify the morphology, the physical or chemical properties in connection with the interfacial reactions and to assess pollution phenomena.

Mass spectrometry (SIMS) | Electron spectrometry (XPS) | Local probes | Profilometry

Mass spectrometry (SIMS) | Electron spectrometry (XPS) | Local probes | Profilometry

Granularity concerns the intrinsic parameters of powders, such as their size distribution, their specific surface, their density and the presence of porosity within the particles themselves or in a finished product. The purely morphological aspects are treated in our “microscopies” sections

Granulometry | Density (pycnometry) | Sorptometry  Hg Porosimetry ? (to be deleted ?)

With our advanced techniques and our own know-how, you can manage risks and optimize the life span of your parts in service.
