Abstract

Nitric oxide detection with Faraday rotation spectroscopy offers excellent sensitivity and high specificity together with outstanding long term system performance. Development of a transportable, cryogen-free, prototype field instrument based on mode-hop-free external cavity quantum cascade laser targeting the optimum NO Q(3/2) transition at 1875.8 cm^-1 is reported . The system shows a minimum detection limit of 5.4 ppb with a lsec. lock-in time constant. Continuous, unattended NO monitoring with >1 hour white noise limited averaging times is reported.
