Determination of ammonia using carbon dioxide laser photoacoustic spectroscopy compared with conventional spectrophotometry.
The potential of carbon dioxide laser photoacoustic spectroscopy and the traditional Indophenol Blue colorimetric method for detecting gaseous ammonia have been compared. The results obtained with the two independent techniques are comparable in the range of concentrations studied.
