Quartz-enhanced photoacoustic spectroscopy based sensor system for carbon disulfide detection using a CW DFB-QCL

, 2014
A compact gas sensor system based on quartz-enhanced photoacoustic spectroscopy (QEPAS) employing a 4.59 µm continuous wave (CW) distributed feedback quantum cascade laser (DFB-QCL) was developed for detection of carbon disulfide (CS2) down to sub-ppmv ...
