Cay's nitrogen analyzer use attention to details
1. Does the sample roll over repeatedly in the distillation unit, is it dangerous for the operator?
The traditional nitrogen analyzer device may be potentially dangerous to the experimenter. However, the nitrogen distiller still produced by Zhejiang Top Company will not. It fully considers the safety issues, and a safety gate device is added in the design to ensure the safety of the experimenters' lives. At the same time, the strong tumbling of the Kaiser nitrogen analyzer is due to the large amount of water vapor entering the digestive tube. At this time, the Kaiser nitrogen analyzer has its own overpressure protection device, which can maintain the internal atmospheric pressure and will not harm the operator.
2. What are the requirements for the water added to the distillation unit?
The water in the distilled water bucket of the Kjeldahl nitrogen analyzer is required to be distilled water or pure water, and if the Kjeldahl nitrogen analyzer is not used for a long time, it is best to drain the water in the distiller.
3. How to solve the problem that the Kjeldahl nitrogen analyzer does not add water to the start distiller?
It is normal to check whether the distilled water bucket is leaking within half a minute of starting up, and it can be filled with air. It is normal to check whether the water level in the distilled water bucket exceeds one third, which is not enough to fill up;
4. When the samples of Kjeldahl nitrogen analyzer are in the digestion furnace, can the digestion furnace be heated vigorously?
When the sample is digested, do not use strong fire. If the sugar or fat content of the sample is high, we must pay attention to controlling the temperature to avoid a large amount of foam spraying out of the Kay flask, which may cause personal danger, and the measurement results will also be affected to a certain extent. The digestion furnace produced by Zhejiang Top Company has water bath heating and electric heating plate heating. The biggest benefit of water bath heating is that it is heated evenly.
5. Will the capacity of the Kjeldahl flask affect the experiment? What is the most suitable Kjeldahl flask can greatly increase the experiment rate.
Generally, we choose 800 or 1000ml Kjeldahl flasks, large Kjeldahl flasks can shorten the ammoniation time, and the heating uniformity and ammoniation efficiency are better. When adding samples, try not to stick the samples to the flask static, so as not to affect the experimental results.
6. When digesting the sample in the digestion furnace, do we choose to use a water bath or a hot plate?
Generally, we use a water bath heating method. The water bath is heated evenly, and the temperature of the Kjeldahl nitrogen analyzer rises steadily, greatly improving digestion efficiency and personal safety.
