A variety of spectroscopic techniques is used in gas analysis and sensing – increasingly important fields, crucial in atmosphere monitoring, emission control and industrial processes efficiency.
Thermal infrared hyperspectral imaging is well suited for the detection, identification, and quantification of industrial stack gas emissions. This application note describes a measurement campaign performed at the Port of Rotterdam with the Telops Hyper-Cam, a commercial high-performance, FTIR-based hyperspectral imaging instrument. Principles of gas detection, quantification, and identification are discussed and computed mass-flow rate results are presented from data acquired at a commercial alkene production facility.
Now smaller, cheaper and more robust, light detection and ranging instruments are being used in new ways, finds Jessica Rowbury
High progress in optoelectronics technology, especially designed for infrared wavelength region (IR), is observed. The use of various spectroscopic methods allows to obtain detailed information on the chemical analysis of the leaking gas. Each of the spectroscopy methods is dedicated to different types of concentration measurements. We encourage you to read the article that explains and presents laser gas leak detection with infrared.
