LOCATION & HYDROCARBONS DETECTION
"MARKER" IS THE ONLY GUARANTEED LEAK DETECTION TECHNOLOGY FOR UNDERGROUND AND ABOVEGROUND STORAGE TANKS AND PIPELINES.
"Marker" surpasses all other test methods because of its superior leak detection sensibility and compatibility with site operations.
The "Marker" test inoculates the tank or pipeline with a small amount of marker chemical. Probes are installed under and around the tank or pipeline allowing the AETECH technician to collect and analyze soil
vapour samples. If a leak has occurred, marker is transported to the soil where it is easily detected by gas chromatography. Using this process the research can identify and locate leaks as small as 0.40 litres per day regardless of the size of the tank.
The "Marker" leak detection method is effective for all types of installations, including tanks and pipes buried under pavement, concrete or buildings.
Sample analysis for marker and volatile organic compounds can reveal the extent of current contamination and the direction of migration. "Marker" can locate leaks to within a few decimetres without any disruption of site operations, even in the largest of bulk storage tanks and the most complex of piping systems.
- Tanks remain in service during the entire test.
- Leak detection sensibility of 0,4 litres per day regardless of tank size of geometry.
- Compatible with any hydrocarbon and virtually any chemical (includes all fuels and crude oils).
- Test results provide specific leak location
- Not affected by hydrocarbons in the soil from previous leaks or spills.
- Leak detection system can be designed to be continuos and automatic (Automated Leak
THE TEST PROCESS
Placement of Probes
Our unique, proprietary method for placing probes horizontally under tanks and vertically adjacent to piping systems is completely safe and noninvasive.
Soils gas samples are taken before any marker is introduced into the system to verify that no other compound similar to the marker is present.
A marker compound is used to determine soil permeability and to verify the sensibility of the test.
A different marker compound is introduced into the tank.
After the marker has had time to disperse, a research technician collects soil gas samples from the probes.
A highly sensitive gas chromatograph is used to analyze the samples of the marker compound. The presence of the marker is clear evidence of a
