The TriOS nanoFlu sensor is an online fluorescence sensor (fluorometer) for precise and selective measurement of coloured dissolved organic matter (CDOM, yellow substances), rhodamine, tryptophan and chlorophyll A in green algae or phycocyanin in cyanobacteria.
It operates by emitting UV light at a set wavelength targeted for specific waterborne flora and fauna. When present, these water constituents will re-emit light at a different wavelength following the excitation from the external light source. The nanoFlu monitors for the presence or change in re-emitted light, which is calibrated to the concentration of the known organic matter.
Long-term stability is ensured by the combination of low power consumption, a hydrophobic nanocoating on the sensing window and a chemical-free anti-fouling solution. Maintenance may also be reduced with the incorporation of air cleaning of the sensing window either from fixed compressed air lines or the standalone TriOS AirShot accessory. Internal reference signals of the LEDs used for fluorescence excitation compensate ageing effects and temperature influences.
The submersible nanoFlu can be used in a range of applications including the real-time monitoring of sea, river or freshwater reservoir systems; incoming/outgoing flow at drinking and wastewater treatment plants; and to detect potential filter membrane leaks during rhodamine testing.
Mounting alternatives include inline fittings, flowcell, small sensor floats and unmanned buoys. Mobile lab staff can couple the nanoFlu with a TriOS G2, which provides power (mains power required) and Wi-Fi connectivity to the sensor for instantaneous indication.
