Abstract
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.Keywords
