The Kjeldahl method for the determination of nitrogen and protein. In 1883, Johan Kjeldahl introduced his "New Method for the Determination of Nitrogen in Organic Bodies", revolutionising nitrogen analysis and setting new standards. Total Kjeldahl Nitrogen (TKN) analysis determines both the organic and the inorganic forms of nitrogen. The analysis starts with an acid digestion of the sample organics, converting organic nitrogen to ammonia.
