Before analyzing the differences between the automatic Kjeldahl nitrogen analyzer and the automatic Kjeldahl nitrogen analyzer, we wanted to understand the Kjeldahl nitrogen analysis steps in several steps. It should be noted that there is no sample digestion.
1. After adding the sample to the machine, add 20 ml boric acid solution to the distilled sample cup.
2. Add 20-50 ml alkaline solution to sample in digestive tube (in this case, the sample is converted into ammonia molecule by ammonium ion).
3. The instrument heats up to generate steam. The sample in the digestive canal is steam heated (where the ammonia molecules are heated and vaporized together).
4. The vapor containing the sample enters the condensing tube and cools down into distilled water into the absorbent in the distilled sample cup.
5. The distillation totaled about 110 mL at the end.
At this step, a friendly reminder is needed. Here, the function of the automatic Kjeldahl analyzer is completed. The distillation sample can be manually titrated to obtain the analysis result. That is to say, the automatic Kjeldahl tester can only perform the above 5 steps automatically. The automatic analysis process of the automatic Kjeldahl analyzer has not yet been completed. Let us continue to go down.
6. The titration system starts working (automatically turning on the photometric lamp and adding the titrant to the distilled sample cup) until the end of the endpoint.
7. Automatically calculate and store analysis results and end.
In the seventh step, all steps of the automatic Kjeldahl analyzer were completed. From the above analysis and comparison, we can see that the automatic Kjeldahl tester only completed the automatic addition of reagents and sample separation; and the automatic Kjeldahl nitrogen analyzer not only completed the automatic addition of reagents and separation of samples. Other tasks include sample separation analysis and storage.
Compared with automatic Kjeldahl nitrogen analyzer, the function of automatic Kjeldahl nitrogen analyzer will be more perfect, the degree of automation is also higher, and the automatic Kjeldahl nitrogen analyzer has high sensitivity, fast analysis speed, and a wide range of applications. It requires less sample, simple equipment and operation, so it is the most widely used instrument for determining the protein content of dairy products and feeds.
