UviLux BTEX Overview
UviLux sensors enable real-time, in situ detection of a wide variety of UV fluorescence parameters, including the BTEX group of contaminants (benzene, ethylbenzene, toluene and xylene).
The compact and highly sensitive fluorometers have excellent turbidity rejection and high ambient light rejection, making them suitable for deployment in groundwater monitoring, as well as natural waters to depths of up to 1000m.

The sensitivity and calibrated range of each UViLux FUEL – BTEX 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

UviLux BTEX FAQs
Which Chelsea fuel sensor do I need?
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 UviLux BTEX sensor is for the detection of highly refined fuels for, typically, inland groundwater studies, FUEL 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 OIL sensor is most appropriate.
