At the same time automatic potentiometric titration technology using potentiometric titration: capillary titration method, the smallest titration volume (controllable in 0.01ml), compared to the manual titration of the smallest volume (controllable in 0.05ml) accuracy is much higher; The endpoint of the titration is determined by measuring the solution potential at the glass electrode and is very accurate. This eliminates the two major human error factors in the titration process and provides the most powerful guarantee for the accuracy of the automatic analyzer. The traditional titration is a manual titration. With burette titration, the indicator determines the endpoint of the titration. Such methods and means have their own drawbacks that cannot be overcome: the accuracy of the burette is not high and the human factors are large; the determination of the titration endpoint is mainly determined by the human eye according to the color change of the indicator, and different analysts have different sensory decisions. Standards, such as the titration results of human error is very large.
We should make full use of the conveniences brought to us by modern civilization and modern science and technology, maximize their superiority, and provide faster and more accurate science for the balanced fertilization of farmland and the creation of high-yield, high-efficiency, green and sustainable agriculture. in accordance with. The superiority of the automatic nitrogen determination instrument: it is to use current excellent scientific and technological achievements as much as possible in the research design process, replace the original artificial control with the software program control; replace the manual operation with the machine operation, making the sample inspection process The stability and precision have been greatly improved, so the accuracy of the test results has also been greatly improved.
Automatic determination of nitrogen from the beginning of the test until the end of the measurement includes a number of steps are automatically completed by the computer, such as the intensity of distillation, time control, and the addition of alkali liquor, etc. are automatically completed, thus ensuring the consistency of the test material Sex. At the same time, the consistency is reflected in the consistency of the absorption solution concentration and volume, which makes the test result more scientific. Elimination of human error in data processing plays an important role in improving the analysis effect of the automatic nitrogen analyzer.
