A spectroscopic trace gas sensor using a distributed feedback diode laser at \u03bb=1.53 μm and based on quartz enhanced photoacoustic spectroscopy technique is described. The sensor is capable of quasi-simultaneous quantification of trace ammonia, hydrogen cyanide, and acetylene (NH 3 , HCN, and C 2 H 2 , respectively) concentrations at \u223c100 ppbv levels with a 4s integration time. The sensor design, responsivity, noise, and cross-talk characteristics are reported.
