Webnitrites, and nitrates. The Total Kjeldahl Nitrogen (TKN) analysis measures ammonia and organic nitrogen. The nitrite and nitrate (NO x) analysis convert all nitrites to nitrates and the result includes the sum of both forms. In order to “speciate” or measure each of the two forms the nitrite and nitrate analyses must be performed individually. WebThe Kjeldahl method is used to determine the nitrogen content in organic and inorganic samples. The procedure involves three major steps: Digestion: The sample is digested in boiling concentrated sulfuric acid, with the addition of a catalyst, until complete dissolution and oxidation. The nitrogen contained in the sample becomes Ammonium Sulfate.
