Abstract

An instrumentation for detection of nitric oxide ( NO ) by direct absorption spectrometry in the parts in 10 9 (ppb) range on its electronic X 2 Π ( ν = 0 ) A 2 Σ + ( ν = 0 ) transition has been constructed around a commercially available fully diode-laser-based laser system producing milliwatts powers of ultraviolet light at 226.6 nm , and its analytical performance has been evaluated. It is shown that the system is capable of detecting NO down to 3 ppb m under low-pressure conditions (at a signal-to-noise ratio of 3 for a signal averaging of 5 s ), which is 2 orders of magnitude below that of any other diode-laser-based absorption technique. The combined line strength of the targeted lines was assessed to 3.1 × 10 18 cm 1 ( molecule cm 2 ) , which supersedes typical line strengths of the fundamental vibrational band and the first and second overtone bands of NO by 2 , 4 , and 5 orders of magnitude, respectively. Also the collision broadening and shift of the targeted lines in NO by N 2 have been assessed.
