Abstract: Ammonia levels in a process gas stream (10) containing carbon dioxide and ammonia are separated and measured with a gas chromatograph (18) containing a photoionization detector (46). The ammonia levels in the process stream are monitored so that the formation of ammonium bicarbonate within the process pipes can be detected.
