KjeldahlAnalytik
Kjeldahl analysis, or KjeldahlAnalytik, is a classical chemical method for determining the total nitrogen content in organic compounds and many inorganic samples. Developed by Johan Kjeldahl in 1883, it remains widely used in chemistry, food science, agriculture, and environmental analysis.
The method combines a digestion, distillation, and titration procedure. In digestion, the sample is heated with
Applications cover a wide range of materials, including foods and feeds for protein content, fertilizers, soil
Advantages of the Kjeldahl method include its broad applicability and reliability for total nitrogen. Limitations include
