Abstract : An automated adaptation of the Berthelot reaction for the analysis of microgram quantities of ammonia is described in terms of a newly developed reagent system incorporating ferrocyanide as a catalyst. This method can be used in the analysis of ammonium in urine. The sensitivity range of the method is 0.5 to 15.0 micrograms/ml. ammonium, and recovery of aqueous standards closely approximated theory. Rates of dialysis of aqueous ammonium standards are constant over the analytical range. Urea and creatinine are shown to be ammonogenically insignificant in the present method. (Author)
