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...

| description | 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 acetylene in the parts per million range. The sensor system was first evaluated for individual H<sub>2</sub>O, CH<sub>4</sub>, and C<sub>2</sub>H<sub>2</sub> detection, respectively. Subsequently, the sensor system was evaluated for simultaneous H<sub>2</sub>O, CH<sub>4</sub> , and C<sub>2</sub>H<sub>2</sub> detection. Finally, trace gas measurements have been assessed and minimum detection limit (MDL) of 1.3 ppmv at 1368.597 nm for H<sub>2</sub>O, 79 ppmv at 1653.722 nm for CH<sub>4</sub>, and 5 ppmv at 1532.83 nm for C<sub>2</sub>H<sub>2</sub> have been demonstrated. The continuous monitoring of H<sub>2</sub>O, CH<sub> 4</sub>, and C<sub>2</sub>H<sub>2</sub> concentration levels for >3 h indicated the stability of the reported multi-gas QEPAS sensor system. |
