Oil spills for example at petrol stations or after accidents lead to widespread contamination of soil, surface water and groundwater with BTXE and PAH. Online fluorometers allow continuous measurements and non-destructive sampling in combination with good specificity and low detection limits. In order to meet the above mentioned requirements, the HydroC™ / PAH is designed as compact and light underwater unit and capable to work on the water surface as well as down to 500 meter or deeper water depth. Applications In-situ measurement of dissolved humic acids, amino acids, BTXE and polycyclic aromatic hydrocarbons PAH motivated by: -supervision and online control of fresh water in waterworks and boreholes - monitoring of waste water in industrial and municipal sewage works - crude oil detection, leakage control at offshore oil pipelines with ROV - fuel detection in natural waters and sewage plants Light source/ Detector Optical Xenon flash lamp at 254 nm (interference filter)/ UV detector at 360 nm (interference filter) Principle An excitation light source generates short flashes. A small part of the emitted fluorescence light coming from the illuminated cone. A band pass filter reduced the spectral range of the fluorescent light according to the special demands of the monitoring task. The incident light is focused onto the silicon UV photodiode which is measured electronically and converted into a voltage signal.
