Humidity enhanced N(2)O photoacoustic sensor with a 4.53 μm quantum cascade laser and Kalman filter

A high-sensitivity N(2)O photoacoustic sensor using a 4.53 μm quantum cascade laser was developed. Sharply enhancement of photoacoustic signal of N(2)O with the increasing of humidity was investigated experimentally. Finally, 2.3 % water vapor was added to the analyzed sample to improve the vibratio...
