eltra Dumas Nitrogen/Protein Analyzer

  Automatic Nitrogen Protein Analyzer by Dumas Method:

  • Automated nitrogen / protein  (and carbon) determination according to the Dumas method
  • Reliable Dumas results in less than 3 minutes and at a low cost per sample
  • Ergonomic design with integrated PC and Tiltable Touchscreen
  • Modern, cost-effective, time-saving and space-saving alternative to traditional Kjeldahl systems
  • High throughput made reliable and cost efficient
  • Available in two configurations: carbon and nitrogen / protein or sole nitrogen / protein

 

food analysis equipment:-

The Kjeldahl method consists of three steps: 1) DIGESTION of the sample in sulphuric acid with a catalyst. The nitrogen contained in the sample is converted to ammonia; ammonium sulphate being formed. 2) DISTILLATION of ammonia released from ammonium sulphate by addition of an excess of sodium hydroxide; ammonia being trapped in a trapping solution (sulphuric acid). 3) BACK-TITRATION of the excess of the trapping solution.
