A new publication from Opto-Electronic Advances, 10.29026/oea.2024.230230 discusses a high-sensitivity LITES-based gas sensor empowered by a novel quartz tuning fork and a multi-pass cell with dense ...
As the name implies, Gas Cells are used to hold a gas or a gas mixture – either for reference measurements or analysis purposes. Gas Cells are commonly used in Fourier Transform Infrared (FTIR) ...
For adequate measurement sensitivity, closed-path optical instruments that sense trace gases need long optical path lengths. While this requirement is easily satisfied for large instruments, it is a ...
