The Kjeldahl method consists of three steps: 1) DIGESTION of the sample in sulphuric acid with a catalyst. The nitrogen contained in the sample is converted to ammonia; ammonium sulphate being formed. 2) DISTILLATION of ammonia released from ammonium sulphate by addition of an excess of sodium hydroxide; ammonia being trapped in a trapping solution (sulphuric acid). 3) BACK-TITRATION of the excess of the trapping solution.
