3.Usage and Application
As a classic method determining nitrogen, Kjeldahl determination is currently widely applied in determining niteogen content in soil, food, agricultural products, fodder and some other substances. When determining samples, the method consists of three steps: digestion—distillation—titrimetric analysis.
