Hydrogen Sulfide Detection in the Midinfrared Using a 3D-Printed Resonant Gas Cell
A fast and reliable photoacoustic (PA) sensor for trace gas detection is reported. The sensor is based on a 3D-printed resonant cell in combination with a continuous wave mode-hop-free external cavity quantum cascade laser to rapidly acquire gas absorption data in the midinfrared range. The cell is...
