QEPAS Sensor for Simultaneous Measurements of H<sub>2</sub>O, CH<sub>4</sub>, and C<sub>2</sub>H<sub>2 </sub> Using Different QTFs
A multi-gas quartz enhanced photoacoustic spectroscopy (QEPAS) sensor based on three quartz tuning forks (QTFs) with different response frequencies for trace gas detection was proposed and experimentally demonstrated. Three near-infrared DFB lasers are used to monitor water vapor, methane, and acety...
