The new cone features UV-emitting LEDs that can detect cold light emission luminescence from fuels and oils, providing a more accurate picture of the ground in real-time.
“Many industrial oils and fuels visibly emit fluorescence under ultra-violet conditions,” explained Lankelma Reporting Engineer Christopher Player. “The UV video cone can detect these emissions at low concentrations, with images streamed lived to a monitor in the CPT truck. Results can be used to enable real-time ground characterisation and to help target additional sampling and testing.”
Pushed into the ground at 0.5cm/s using CPT equipment, the video cone has a camera and LEDs sitting behind a glass window. Alongside fuel and oil contamination, the cone allows particles such as shells and sand grains to be distinguished easily; small voids and gas bubbles are also visible.
We will be showcasing our contaminated land investigation techniques at Brownfield Briefing’s Effective site investigation and data management conference, being held at the De Vere Colmore Gate in Birmingham on 24-25 May. For more details, visit the conference website.
