The KT 200 KjeltecTM distillation unit provides a simple and reliable solution for safe and semi automatic distillation.
The addition of alkali and the time interval for distillation can be pre-programmed for consistent results independent
Parameters: Kjeldahl Nitrogen/Protein, ammonium, TKN etc
Sample types: Raw materials and finished products in Food, Feed and Agriculture
Method/principle of analysis
1) The sample is first digested in strong sulfuric acid in the presence of a catalyst, which helps in the conversion of the amine nitrogen to ammonium ions. 2) The ammonium ions are then converted into ammonia gas, heated and distilled. The ammonia gas is led into a trapping solution where it dissolves and becomes an ammonium ion once again. 3) Finally the amount of the ammonia that has been trapped is determined by titration with a standard solution, and a calculation is made.
High safety with semi-automated Labtec Line solutions
The KT 200 Kjeltec is safe to use. The unit is equipped with sensors for safety door and level/overpressure sensors for the steam generator. The door completely covers the area in front of the operator and the unit can not be operated with the door open. The SAfE (Steam Addition for Equilibration) technology improves safety by a mixing procedure, reducing the exothermic reaction between alkali and acid during distillation.
