UV Oil Detection
Crude oil detection with Vertek's LVUV ultraviolet (UV) LED technologies is the cleanest and most efficient method of monitoring the Gulf of Mexico oil spill by discriminating the crude oil from sand, mud, sea life, and saltwater.
Much of the crude oil and tar balls that are contaminating our beaches are virtually undetectable with the naked eye. Vertek LVUV spotlights, floodlights, and series lamp technologies enable oil spill cleanup crews and supporting scientists to easily spot washed up oil and tar balls that have been mixed with wetland mud and beach sand. Many natural beach materials will fluoresce, or glow, under UV illumination, so it is crucial that the UV light being projected be tuned as closely as possible to the hydrocarbons present in the washed up crude oil product. Vertek's UV Oil Illuminators are not only the most powerful UV sources available, but also the only illuminators tuned for crude oil hydrocarbon detection.
The Vertek LVUV crude oil LED Illuminator series is designed to induce the signature fluorescence of the crude oil and its products floating in the Gulf of Mexico, in wetlands and marshes, and washing up on beaches in trace amounts. The beach products can be detected and monitored over time by "fluorescing" the area at each low tide. Regular monitoring enables status reports to be written and filed for public awareness based on facts, not guesses. While tar can be an obvious visual indication of coastline contamination, it is likely that vast areas of beach and wetland coastlines are being contaminated - without any visual indications. The Vertek LVUV series illuminators provide real-time contamination detection enabling cleanup crews and scientists to monitor the effectiveness of cleanup efforts and make immediate decisions regarding cleanup strategies and methods, eliminating the delay associated with sampling and laboratory analysis.
The LVUV series spotlight from Vertek is the highest power UV spotlight on the market. That means less time setting up your cleaning operation and more time getting the job done. Yes, you can monitor progress day-to-day of oil spill contamination and cleanup on your beach or wetland.
Hydrocarbons fluoresce, or glow, under specific wavelengths of ultraviolet light. The Vertek Division of Applied Research Associates, Inc. has long been producing Fuel Fluorescence Detection modules for our Cone Penetrometer (CPT) Systems to characterize hydrocarbon plumes below ground.
Recently we have developed a high power Low Voltage UV (LVUV) spotlight based on our CPT system that can be hand held or outfitted to any vehicle, land or sea, to scan above ground or on the water surface for contaminants.
With Vertek's LVUV Spotlights, scientists and cleanup crews are able to spot washed up oil and tar that has been mixed with mud and sand. Much of the oil and tar that is contaminating our beaches cannot be seen, even when right in front of you in full sunlight! Deposited tar balls, often partially covered by sand, glow bright orange and yellow under the powerful Vertek LVUV series spotlights. Crude oil and other heavy petroleum hydrocarbon products can also be detected with LVUV illuminators (see chart).
