Optical Gas Imaging (OGI) is currently the preferred technology for detecting leaks and emissions of hydrocarbon compounds worldwide. This thermal camera-based technology uses an infrared bandwidth filter in the spectral absorption range of all volatile organic compounds (VOCs). American regulations, both state and federal, are transitioning from conventional methods, such as sniffers, to visualizing leaks and detection using OGI cameras. The Federal Environmental Protection Agency (EPA)’s federal regulation approved in 2016 states that this is the Best System of Emissions Reduction (BSER).
