UV-visible spectrophotometry
This spectrometer measures the absorption of visible UV on liquids and solids, in a conventional tank, but also takes offset measurements directly in the solution via a probe and optical fibers.
Characteristics
As well as standard measurements on tanks, this UV-Visible spectrometer also measures:
- on radioactive substances (99Tc, 237Np, etc.)
- in-situ during radiation by the beams of the ARRONAX cyclotron
- offset by a distance of 2 m to 20 m
- on film, with the possibility of producing a base through 3D printing
- simultaneous with electrochemical assembly (preparatory EC, cyclovoltametry)
- in a wavelength range of 200 to 900 nm
- with an optical density sensitivity of 1.10-3
CARY 4000 spectrometer
Applications
- Determining the dose of radiation received by Fricke in situ dosimetry
- Monitoring oxidation/reduction of radioactive or other species (red-ox degree, coordination sphere)
- Analysis of degradation of polymers exposed to radiation
- Detection of dissolved gases, like SO2
- Dosage of H2O2 and other oxidants (Ghormley method, titanium methods)
Other possibilities :
- Study of transition metals and their complexes
- Measurement of the thickness of polymer films

We also have 5 Shimadzu UV1200 spectrometers for practice tutorials and training, as well as an Agilent cary60 spectrometer coupled with an Autolab101 (metrohm) potentiostat that takes electrochemical and UV-Vis measurements on only a few hundred microliters.
