Kjeldahl System
Our Kjeldahl systems are specialized laboratory instruments designed for the determination of nitrogen content in organic and inorganic samples, particularly in food, agriculture, and environmental analysis. Named after its inventor, Johan Kjeldahl, this method involves a series of chemical reactions where nitrogen is converted into ammonia and then quantified. The system typically consists of a digestion unit, a distillation unit, and titration equipment. In the digestion step, the sample is heated with concentrated sulfuric acid, causing the nitrogen to convert into ammonia. The ammonia is then released through steam distillation and collected in an acidic solution. Finally, the concentration of ammonia is determined by titration with a known solution. Labotronics Kjeldahl systems offer various automation levels, from manual to fully automated setups, streamlining the time-consuming and labor-intensive Kjeldahl process.
