Compared with other instrument products, the working environment of the nitrogen determination instrument is relatively harsh. In operation, the nitrogen determination instrument needs to withstand the tests of concentrated sulfuric acid, boric acid, sodium hydroxide and other corrosive bodies and heating, so this requires the determination of nitrogen. The quality and safety performance of the instrument are very high. In the past, the nitrogen analyzer used in the production was manual operation, and the safety was difficult to guarantee. Therefore, the control method has changed and the microcontroller has been used for control.

The disadvantages of the manual control of the nitrogen determination instrument can be said to be that the safety performance is not high, harmful gases in the reaction process can cause harm to the human body, and on the other hand, the accuracy is also low, since the refilling and the like rely on human eyes, therefore In the process of work, it is inevitable that errors will occur. Therefore, the accuracy and safety of the early fixed nitrogen analyzers are also poor. Now, with the advancement of science and technology, nitrogen determination instruments are used in various industries and are commonly used in various laboratories. An instrument product, therefore, the improvement of its control methods can meet the requirements and goals of modern precision science experiments.
At present, more and more nitrogen determination instruments with automatic control methods are used in the laboratory, which not only improves the control accuracy, but also precisely controls the dosing and distillation time. It also provides a good basis for batch repeat testing. In terms of safety performance, the new type of nitrogen determination instrument has determined the general aging phenomenon of the silicone tube and the aging of the rubber tube. It ensures that the pipeline does not leak, ensures the recovery rate of the instrument, and especially ensures the recovery of low concentration samples. rate. Now, through the improvement of the control method and safety of the nitrogen determination instrument, the nitrogen determination instrument has higher safety, more flexibility, and the test process and operation are simpler, and the accuracy of detection has also been greatly improved. Therefore, the fully automated Kjeldahl analyzer is now more popular in the laboratory.
