An ammonia probe has been used to replace the distillation‐titration procedure for estimating the ammonium content of Kjeldahl digest solutions. A procedure is described for estimating the total nitrogen content of barley, malt, wort and beer. The semi‐micro digestion stage is performed as a batch procedure and the ammonium content of the acid digest estimated automatically in a continuous flow system at a rate of 60 samples per hour. The method is more rapid than the classical distillation‐titration procedure and gives results of comparable accuracy and precision.
