Laboratory Digital Weighing Scale Price - Auto Kjedahl Nitrogen Analyzer – NANBEI
Laboratory Digital Weighing Scale Price - Auto Kjedahl Nitrogen Analyzer – NANBEI Detail:
Principle
The organic compound is heated with these sulfuric acids to convert the nitrogen in the sulfuric acid into ammonium sulfate. In the middle, potassium sulfide is often added to the mixture to increase the boiling point of the intermediate product. It will become colorless and transparent (it is dark at the beginning). Add a small amount of sodium salt to the resulting solution and stir. ) Will be determined by back titration: the reaction of the cathode tube will interact with the solution in six acids. The result can be obtained by transforming the cause.
Performance Characteristics
1.Manual/auto double-mode switch and automatically adding quantitative alkali liquor and boric acid absorbent solution.
2.10 experimental procedures can be stored to meet users’ different requirements. Distillation time can be set at will. After distillation completion, it will give an alarm automatically.
3.Automatic cleaning system realizes intelligent pipeline cleaning function which make measuring accuracy higher.
4.Perfect safety protection system can measure and protect over-temperature and over pressure of distiller and pipeline.
5. Intelligent design of facilities around Kjedahl Apparatus contains safety protection design and non-existence prompt function.
6. Intelligent cooling water control system can control and inspect cooling water
7. Emergency stop operating function for emergency
8. Automatic inspection of failures and intelligent audible and visual alarm system
