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.


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


  • 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
