A laser-based hydrogen (H2) sensor using wavelength modulation spectroscopy (WMS) was developed for the contactless measurement of molecular hydrogen. The sensor uses a distributed feedback (DFB) laser to target the H2 quadrupole absorption line at 2121.8 nm. The H2 absorption line exhibited weak collisional broadening and strong collisional narrowing effects. Both effects were investigated by […]

“Oil and Gas Innovation sits down with Dr. Peter Geiser, Chief Technology Officer at NEO Monitors AS, to discuss among other things, their Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology. What NEO Monitors does is help companies with gas sensing, but because they are using lasers, or what they like to call “contactless” technology, it […]
