Diode laser system for measurement of gaseous ammonia in ambient air.

F Cappellani1, G Melandrone, G Restelli.   

Abstract

The use of a second harmonic diode laser system for monitoring gaseous ammonia in tropospheric air is discussed. Using a 96 m White cell operated at 13 torr pressure in flow mode, a minimum detectable concentration lower than 1 ppbv was obtained.The NH3 mixing ratio was determined by simultaneous spectroscopic analysis of an atmospheric CO2 line used as a built-in calibration standard.
