Parts-per-Billion Detection of Hydrogen Sulfide via Cavity Ring-Down Spectroscopy
Rapid and precise detection of hydrogen sulfide (H<sub>2</sub>S) at trace levels is critical for industrial safety and environmental air quality monitoring, yet existing methods often struggle with cost, speed, or sensitivity. A cost-effective cavity ring-down spectroscopy (CRDS) analyze...
