Of all the colorimetric methods proposed for the determination of ammonia nitrogen, the ones which use the Berthelot reaction are by far the preferred methods. The great sensitivity of this reaction to contaminations due to atmospheric ammonia is the only relevant criticism that can be made about it. The use of the Technicon analyzer is an effective means of protection against such contamination. The authors tried to adapt this reaction to the automatic determination of the ammonia nitrogen.
