Measurement and Testing
Conference to highlight benefits of photoacoustic laser spectroscopy for air pollution monitoring at refineries and petroleum plants
Apr 27 2022
Next generation air measurement technologies are making it easier to identify air pollution leaks from pipes, seals, and other areas at industrial facilities. With sub-ppt detection limits, photoacoustic laser spectroscopy is a highly sensitive method for monitoring trace levels of air pollutants in ambient air. Photoacoustic laser spectroscopy is an optimal technology for detecting low levels of harmful non-criteria pollutants such as benzene, formaldehyde, and hydrogen fluoride among others. Typically, the ambient concentration levels of those gases are in the low ppb range which sets strict performance requirements for monitoring technologies. Gasera has demonstrated sub-ppb level detection limits for multiple gas compounds including benzene, formaldehyde, and hydrogen fluoride in a standalone analyser which includes gas sampling, low power consumption, and an easy-to-use user interface. Zero-background measurement enables drift-free operation over a wide dynamic range with along re-calibration interval. Gasera’s photoacoustic laser spectroscopy analyser, the GASERA ONE can be viewed on PEFTEC stand J1, and will feature in the Conference presentation by Dr Jaakko Lehtinenat 12:05pm on day two of PEFTEC 2022, 9th June.
