TKN determination in water and wastewater
SpeedDigester K-439, Kjel Line and MultiDist: Steam distillation and Potentiometric determination of Total Kjeldahl Nitrogen (TKN) according to the kjeldahl method in water and wastewater along with determination of Limit of Detection (LOD) and Limit of Quantification (LOQ).

Freeze-dryers were initially intended to be used with water as a solvent. With new applications, freeze-drying is consequently being used more and more in combination with organic solvents instead of water. Organic solvents and inorganic acids and bases are often used in research and development prior to lyophilisation of the sample. The behavior of these new types of samples during freeze-drying must therefore be considered prior to the process.
Total Kjeldahl Nitrogen determination in wastewater
In this application note, an easy and reliable method for the determination of TKN in wastewater is introduced: Samples are digested with the SpeedDigester K-439 using Kjeldahl tablets Titanium. A steam distillation protocol followed by a colorimetric titration in boric acid is performed with the MultiKjel and Metrohm Eco Titrator, respectively, providing reliable and reproducible results.
