Dexsil's PetroFLAG is a revolutionary new field portable test method for determining hydrocarbon concentration in all types of soil.
The test is ideal for site assessments, tank removal procedures, oil spill clean-up and for monitoring the progress of remediation activities. In minutes, users can obtain quantitative data on a sample contaminated with any type of petroleum hydrocarbon.
Economically locate & define hydrocarbon contaminated soil
Using PetroFLAG, environmental professionals can determine hydrocarbon contamination levels at a fraction of the cost of laboratory analysis. An additional cost benefit comes from the field portability of the kit, tests can be run on-site and provide real-time results to facilitate clean-up activities and assist on-site project management.
PetroFLAG also provides high throughput capabilities; up to ten tests can be performed concurrently so one user can easily complete 25 samples in an hour. Everything required to run the test, including the chemical reagents, fits in the convenient carrying case. The test procedure uses no chlorofluorocarbons and all spent reagents can be easily disposed of.
Petroflag support a wide variety of sampling strategies
PetroFlag is easily used at contamination sites where a variety of sampling strategies are to be employed. It is useful at sites requiring lateral and vertical definition of soil contamination plumes throughout the vadose zone, including sites that are being drilled or axcavated for sampling.
PetroFlag is well suited for large sites where a grid sampling plan is the strategy of choice. In many cases a grid sampling plan would be ruled out due to the high cost of laboratory analysis. PetroFlag allows the grid strategy to be used while providing the user with meaningful data for on-site decision making prior to submitting samples for expensive laboratory analysis. The use of PetroFlag for grid sampling will help to economically locate and define the extent of contanimation, locate and define hot spots and help delineate the zero line. This can prevent unnecessary drilling and sampling and will eliminate re-mobilization costs associated with waiting for tracking and evaluating the success of soil remediation projects such as bioremediation.
Petroflag test methodology
PetroFLAG relies on a unique system of extraction solvents, analytical reagents and a hand-held, battery-powered analyzer to read contamination levels directly in parts per million (µg/g). The test is performed using three simple steps: extraction, filtration and analysis. In the first step a proprietary solvent system that does not contain chlorofluorocarbons effectively extracts hydrocarbons from a variety of soils ranging from course sand to marine sediment and clay. Moisture content has no effect on extraction efficiency. The second step filters out all suspended materials from the extract so that they don't interfere with the test results. Finally, a developing solution is added and the soil extract starts to react and develops a response in proportion to the amount of hydrocarbon contained in the soil sample. Within ten minutes the developing solution equilibrates and a reading can be obtained using the analyzer. If the type of hydrocarbon is known, then the specific response factor can be selected from the on-board menu to calibrate for the analyte. If the contaminant is unknown a general hydrocarbon screen can be performed by selecting a conservative response factor and using the "screen" mode. This will provide a conservative, general screening result that lets the user know if contamination is present and if so, at what relative concentration.
