UviLux FUEL- PAH
The Chelsea Technologies UviLux Fuel – PAH sensor is for the detection of the leakage of traditional fuels into streams, rivers and ports. UviLux sensors enable real-time, in situ detection of a wide variety of UV fluorescence parameters, including Polycyclic Aromatic Hydrocarbons (PAH). The compact and highly sensitive fluorometers have excellent turbidity rejection and high ambient light rejection, making them suitable for use in a wide variety of natural and process waters to 1000m depth.
Features & Applications

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
What is PAH?
Petrogenic PAHs are present in petroleum and its by-products, widespread due to storage, transport, use, and leakage of crude oil and its products.
Whereas the Chelsea Technologies FUEL-BTEX sensor is for the detection of highly refined fuels for, typically, inland groundwater studies, the FUEL-PAH sensor is more for the detection of the leakage of traditional fuels into streams, rivers and ports. For unprocessed fuels at the source (i.e. upstream at source), the Chelsea UviLux OIL is the appropriate sensor.
Do I need to measure FDOM too?
In practice, Chelsea Technologies recommends combining the UviLux FUEL-PAH with the UviLux-FDOM, to allow differentiation between PAH signal and FDOM signal. The PAH and FDOM signal does overlap, and the use of multiple sensors will give more differentiated datapoints.
