2. Theory According to the Kjeldahl theory, there are three processes including digestion, distillation and titration in the test. The Kjeldahl Distillation Unit is able to execute the distillation process automatically. The chemical reactions listed below occur after a sample has been completely digested. ⎯... -
Page 7: Installation Instruction
IV. Names of Kjeldahl Distillation Unit Parts The Kjeldahl Distillation Unit is a special system, which can automatically distill the completely digested samples and show the workflow in real time mode. The system mainly consists of a microcontroller, steam generator, distillation system and an automated reagent dispensing system. The exterior structure is shown in the following diagram: Fig. - Page 8 The power supply should meet the specified requirement, which must have ground wire, independent power switch and fuse protection to guarantee the safety of operators. The Kjeldahl Distillation Unit should be far away from any big-scale electric equipment, and its working environment should be free of vibration and electromagnetic interference, in which there is no corrosive substances.
