Abstract
To analyze continuously a stream from a bioreactor for the concentration of ammonium ion, the broth is adjusted to high pH and conveyed to a small mixing chamber containing an ammonia electrode. The system has a delay of only 1 minute and a time constant for response of approximately 1 minute. Fouling and leaching of the electrode membrane are prevented by a small, sealed air gap between the electrode and the sample stream; membrane life is at least five days.
