Published By | Publication Date | Number of Pages |
DIN | 2012-11 | 16 |
This European Standard specifies the determination of Kjeldahl nitrogen according to the Kjeldahl procedure in sludge, treated biowaste and soil. Nitrate and nitrite are not included. Compounds with nitrogen bound in N-N, N-O linkages and some heterocycles (pyridines) are only partially determined. NOTE Typical LOQ is 0,1 % N; typical LOD is 0,03 % N (using 0,25 N sulfuric acid for titration).
