Trace Gas Analysis with Quartz-Enhanced Photoacoustic Spectroscopy
For the analysis of trace gases, a non-contact quartz-enhanced photoacoustic spectroscopy (NC-QEPAS) method has been demonstrated. The NC-QEPAS seeks to address the limitations of the quartz tuning fork (QTF), which is constrained in its application for sensing corrosive and dusty gas.
