Abstract

Measurements of CO and NO are reported using thermo-electrically cooled, mid-IR quantum cascade lasers operating near 4.6 and 5.26 μm, respectively. Measurements of NO in H₂-air and CH₄-air flames at temperatures of approximately 780 and 1600 K are presented along with room-temperature CO measurements. Sensitivities on the order of 1.5 ppm-m are achieved in the case of NO in a flame using a balanced ratiometric detection technique. Comparisons between measured and predicted water-vapor interference is discussed.
