BÜCHI Labortechnik AG

The determination of TKN (total Kjeldahl nitrogen) in water and waste water is a routine procedure for quality assurance and inspection. Here, a reliable procedure for the colorimetric TKN determination in water, according to ISO 5663, AOAC 973.48, and EPA 351.3 is introduced.
The sample is digested with sulfuric acid and the Kjeldahl Tablet Titanium using the KjelDigester K-449, followed by distillation and titration with the KjelMaster system K-375 / K-376 equipped with the colorimetric sensor using the Sher mixed indicator.
