The KT 200 Kjeltec™ Distillation unit provides a simple and reliable solution for safe and semi-automatic distillation. The possibility to pre-program alkali addition and distillation time supports the production of accurate results independent of operator. Accurate bellows pumps give long term stability in reagent delivery.

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.
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.
With an integrated sampler system the Kjeltec 8400 gives you the ultimate solution for automation in the Kjeldahl laboratory – regardless of sample throughput.
