Photonic Gas Analysis Probes Upgrades in Sources and Detectors
The hunt is on for better gas analyzers, driven by growing demands. For instance, hydrogen sulfide, an industrial byproduct, has a permissible worker exposure limit of 20 ppm in a confined space, according to OSHA. Increasingly stringent emission regulations for greenhouse gases such as methane are also driving adoption. Photonics-based gas analysis employs a number of techniques and component technologies, including light sources and detectors, along with an array of mirrors, lenses, gratings,...
