LCS Valoris offers you its expertise and flexibility for all your industrial analysis requirements and research projects.

It’s a one-stop shop where you can discuss your problems and find the best person in the laboratory to address them. Cooperation with a university laboratory gives a company access to specific skills and unique laboratory resources. What’s more, you can reduce your R&D costs as we are eligible for the Research Tax Credit (CIR).

LCS Valoris undertakes to treat your request as confidential. A confidentiality agreement can be signed before discussing the technical or commercial aspects of your project in detail.

The sectors in which we operate:
energy, automotive, environment, pharmaceuticals, medical devices, cosmetics, plastics and polymers, aeronautics, general industry

Our technical resources: Our 4 platforms

Four shared measurement platforms support the daily work of LCS teams. Particularly noteworthy is the IR platform (VISIO), based on the laboratory’s longstanding expertise, which has reached a very high level of maturity, recognized internationally. The solid NMR development well underway has been located since early 2017 within a shared platform with the LCMT Laboratory, the Centre Commun de Résonance Magnétique Nucléaire Caennais – CCRC. The other two platforms concern synthesis and physical characterization (created in 2009), as well as catalysis and chemisorption.

Residue analysis of PVC gloves

Problem: gloves causing skin allergies

Proposed solution: search for undesired compounds using IR spectroscopy (ATR), comparing defective gloves with compliant ones.

Location of glove samples Difference spectra resulting from IR analysis of glove samples

Answer given: presence of organic compounds containing bromine (probably from a Bromodan-type insecticide).

Residue analysis of medical leaflets

Problem: determine the nature of an unwanted deposit using IR (Transmission) spectroscopy, by comparing a medical leaflet with a deposit with grease residue from a printing press, or clean machine oil.

Comparison of IR spectra of dark particles (deposited on medical leaflets), machine grease with residue and clean machine oil.

Answer given: comparative analysis of the spectra clearly shows that the dark-colored particles found on the medical leaflets are of the same nature as grease with residues of

Analysis of polymer presence in aqueous solution

Problem: polymer dosage in aqueous solutions

Proposed solution: calibration of polymer concentration in solution by IR spectroscopy (transmission) and screening of different samples with unknown polymer content.

Example of a solution containing the polymer to be measured Calibration of polymer in solution as a function of the area of the polymer’s characteristic band

Answer provided: Determination of polymer concentration in the various samples to enable its traceability in the process.

Analysis of oil residue inside an engine crankcase

Issue: whether the oily residue comes from the decomposition of engine grease or from an external source

Proposed solution: comparison of oily residue and grease by IR spectroscopy (ATR)

Comparison of IR spectra of oily deposit and engine grease. Demonstration of the presence of esters1 characteristic of fat degradation in an oxidizing environment

Answer given: the oily deposit results from grease degradation.

Analysis of greasy residues on car circuit boards

Problem: Analysis of grease residues on car circuit boards to characterize the degradation of grease after use.

Proposed solution: analysis of the areas concerned using an infrared microscope for precise zoning. Non-destructive analysis carried out directly on the circuit board.

Map areas to be analyzed IR spectra of targeted areas

Answer provided: allocation of bands and integration of bands to determine changes in the ester/polyarylurea ratio in order to monitor changes in the relative composition of fat.

Applications: electronics, aeronautics, automotive
