Highly sensitive UV fluorometer for real-time, in situ detection of aromatic hydrocarbons (PAH), CDOM, Tryptophan-like fluorescence (TLF), BOD or Optical Brighteners.


UviLux sensors enable real-time, in situ detection of a wide variety of UV fluorescence parameters, including: Polycyclic Aromatic Hydrocarbons (PAH), BTEX, CDOM, Tryptophan-like fluorescence (TLF), BOD and Optical Brightening Agents (OBA). The compact and highly sensitive fluorometers have excellent turbidity rejection and high ambient light rejection, making them suitable for use in water and wastewater treatment works, as well as natural waters at the surface and to depths of up to 1000 m.


Features & Applications



  • Pollution surveillance & investigative monitoring
  • Point source pollution tracking
  • Hydrocarbon monitoring in ports & coastal areas
  • Road and airport apron run-off monitoring
  • Pollution ingress into infrastructures
  • Monitoring industrial effluent discharge in natural waters



Technical Specification




The sensitivity and calibrated range of each UViLux sensor has been standardised by cross-correlating each calibration solution against a certified reference standard of quinine sulphate using a bench-top spectrofluorometer.  Fluorescence is reported in Quinine Sulphate Units (QSU), where 1 QSU is equivalent to the fluorescence intensity recorded from 1 ppb quinine sulphate at an excitation wavelength of 347.5 nm and an emission wavelength of 450 nm. Factors are provided for selected compounds to convert the fluorescence output from QSU to ppb of the compound of interest
