Electron Paramagnetic Resonance

Keywords: resonance, paramagnetism, EPR, ESR, electron spin, radicals

Visit

Summary

The presence of paramagnetic centers in the matter, in solution, in living tissues or fluids allows using the electron paramagnetic (spin) resonance (EPR or ESR) to obtain informations about the structure, the defects, the kinetic of reaction, of polymerization and of (photo)degradation.

Enzyme Activity & Screening Platform (PACE)

Keywords: biocatalysis, screening, analytical chemistry, assay, enzyme
 

Visit

Summary

The screening platform makes it possible to automatically determine enzymatic activities in parallel in 96-well microplates. It also makes it possible to carry out analytical assays in microplates of compounds of interest. In the context of the search and / or quantification of an enzymatic activity such as the determination of a concentration of an analyte in solution, the compounds having a chromophore, a fluorophore or a luminophore can be assayed.

Optical Spectroscopy

Keywords: Optical characterization, photoluminescence, reflectivity, transmission

Visit

Summary

 Study of optical properties through optical spectroscopy, analyses, interpretations and simulations. The optical signal could be recorded with a temporal or angular resolution, as a function of the wavelength, the polarization, the excitation power or the temperature of the sample.

Surface Analysis by Electron Spectroscopy (ESCA)

Keywords: Surface analysis; Electron spectroscopy; identification of phase and oxidation degree; calculation of atomic concentration

Visit

Summary

The ESCA platform, open to academic laboratories and companies, performs elemental and functional chemical analysis of the extreme surface (≤10nm-depth) of all types of solid materials. This platform includes ultrahigh vacuum equipment allowing the structuration of surfaces and their in situ analyses by electron spectroscopy enabling the identification of all elements (except H and He) and the nature of their bonds, their local environment and/or their degree of oxidation, the highlight of superficial segregations and the determination of atomic concentrations.

Vibrational Spectroscopy

Keywords: Vibrational spectroscopy, FTIR, Raman, chemical bonding

Visit

Summary

 Infrared and Raman vibrational spectroscopies allow to characterize intramolecular bonding of molecules either gaseous, liquid or solid (powder or massive). Those technics are non-destructive and sensitive at the microgram scale of sampling.
