      abstract = {This book provides a comprehensive survey of the Kjeldahl  method and its modifications. It covers all relevant  topics, including sample digestion and its variables,  distillation and determination of ammonia, equipment  development, and concludes with a review of the literature  published on the method. Since its introduction in 1883,  the Kjeldahl method has been an essential analytical tool  for nitrogen determination in research, academic and  industrial laboratories. This makes the history of the  Kjeldahl method of outstanding relevance to graduate  students, postgraduate students, researchers, teachers, and  laboratory staff in the fields of analytical chemistry,  food/feed analysis, animal/human nutrition, soil/water  analysis, and so forth. "This method has probably been  applied in one modification or another to every possible  form of nitrogen, and in perhaps more laboratories than  almost any other single type of analytical method" (Kirk,  1950).},
