Cooking process is environmentally friendly and non-toxic. In the event of a change in the previous digestion process, poisonous gases are spilled around, polluting the environment and compromising the health of analysts. It can be seen that the designers of the automatic nitrogen determination instrument did indeed fully consider the theme of environmental protection as a contemporary society during the development process. Due to the closed heating and tail gas recovery processing technology, all the toxic and harmful substances such as sulfuric acid vapor and sulfur dioxide gas generated during the digestion process will be sucked back into the absorption liquid for non-toxic and harmless treatment. Therefore, the automatic nitrogen determination instrument is The whole cooking and heating process will not cause pollution to the environment, and it will also play a very good protective role for the laboratory personnel.
Sterilization conditions are uniform and stable. The fully automatic nitrogen determination instrument adopts a controllable constant-temperature heating technology and simultaneously heats twelve samples in a full range of isolated radiation. (The number of samples may be different when using different types of cooking apparatus.) ), With the automatic control of time, so that the heating intensity and time have a unified guarantee, such cooking conditions for the stability of the analysis results, play a crucial role. In the boiling process of fully automatic determination of nitrogen, each sample can be uniformly stable and consistent conditions of heating, a unified program temperature mode can make the sample can be slowly heated without bumping, and there is a strict maximum temperature limit (less than At 400°C, nitrogen above the warm leaching may decompose and volatilize.
Fully automatic nitrogen determination instrument adopts the above two general design features of the above-mentioned digestion and cooking conditions and the environment-friendly and non-toxic two major design features and related technologies are favored by many experimental operators. The users are more convenient and simple, and have no influence on the data results. Small precision, which also makes it highly praised in the structural analysis of soil fertility and related research.
How to Realize Soil Fertility Analysis with Automatic Nitrogen Determinator
The determination of nitrogen is not just a measurement of nitrogen content in grain, oil, and food. As we all know that nitrogen is also abundant in soil, the instrument is also widely used in soil nitrogen content. However, for a long time people have been using the Kjeldahl apparatus for distillation measurement. Since this method has a stable measurement result, good reproducibility, and high correlation with soil fertility, it is normal to use it widely. With the rapid development of science and technology, on this basis, people continuously inject new materials or the automatic nitrogen determination instrument finally developed by the process further improves the detection speed and the accuracy of the results. The main features of automatic nitrogen determination instrument:
