The method by which the Vertek Fuel Fluorescence Detector acts as a crude oil detector. The FFD is able to detect underwater plumes of crude oil and the density of the plume using fuel fluorescence.
Vertek’s dual down hole Fuel Fluorescence Detector (FFD) detects the fluorescence produced by aromatic hydrocarbons when excited by an ultraviolet (UV) light source. Pushed with Vertek Cone Penetrometer Technology (CPT) equipment, the UV LED FFD significantly reduces the time needed to detect and delineate the extent of hydrocarbon fuel spills or leaking storage tanks.
Vertek's fuel fluorescence detector (FFD), is used to delineate hydrocarbon contamination versus depth. The FFD detects the fluorescence produced by aromatic hydrocarbons when excited by an ultraviolet light source.
Typical contaminants detected by the FFD are jet fuel, diesel, unleaded gasoline, home heating and motor oil. Total petroleum hydrocarbon (TPH) values as low as 100 ppm can be detected in sandy soils.
The FFD contains dual downhole photomultiplier tubes (PMTs), which permits differentiation between lighter fuels, which fluoresce more intensely at short wavelengths, and heavier fuels, which fluoresce more intensely at longer wavelengths.
The FFD provides a continuous, real-time output of fluorescence over the entire depth of investigation. Multiple FFD profiles across a site can be combined to develop a three-dimensional model of the plume. Vertek's FFD is coupled to a CPT probe, providing detail soils information simultaneously with FFD data.
