摘要：

A trace gas sensor based on quartz-enhanced photoacoustic spectroscopy with a quantum cascade laser operating at 4.55 mum as an excitation source was developed. The sensor performance was evaluated for the detection of N2O and CO. A noise-equivalent (1sigma) sensitivity of 4 ppbv N2O with 3 s response time to (1-1/e) of the steady-state level was demonstrated. The influence of the relevant energy transfer processes on the detection limits was analyzed. Approaches to improve the current sensor performance are also discussed.
