How does the Kjeldahl nitrogen analyzer test nitrogen content?

In many fields such as food processing and feed production, accurate determination of nitrogen and protein content is crucial, which is directly related to product quality and safety. As a professional instrument for determination based on the Kjeldahl nitrogen determination method, the Kjeldahl nitrogen analyzer has become a powerful assistant for detection work in related fields with its unique advantages.

The Kjeldahl nitrogen analyzer integrates the distillation to condensation process that originally required manual operation into one device for automatic execution, greatly reducing the workload of detection. Its application range is extremely wide, covering food processing, feed production, tobacco, animal husbandry, soil and fertilizer, environmental monitoring, medicine, agriculture, scientific research, teaching and other fields, providing strong support for nitrogen and protein analysis in these fields.

Functional characteristics and performance advantages of the Kjeldahl nitrogen analyzer:

(1) Intelligent operating system and automated process

The instrument uses the Android 10 system and is equipped with a 7-inch touch screen for easy operation. In terms of liquid addition steps, it can automatically complete operations such as adding alkali, adding boric acid, adding diluent, adding distilled water, etc.; in terms of experimental steps, it can automatically complete distillation and absorption operations, making the detection process more efficient; in terms of protection functions, it has multiple protections such as evaporator water level monitoring, anti-dry burning protection, condensate flow rate monitoring, condenser temperature detection, etc. to ensure the stable operation of the instrument.

(2) Efficient data processing and networking functions

The Kjeldahl nitrogen determination instrument has a built-in 16G high-capacity storage, which can store 5 million test results. The results are presented in Excel form and can be directly copied to a USB flash drive. It also supports batch printing and uploading. The high-speed thermal printer can automatically print the test report after the test is completed, and the instrument has a wifi networking function, and the test results can be directly uploaded to the platform.

(3) Energy-saving and environmentally friendly design

The program controls the opening and closing of the condensate to save water, and realizes low flow rate alarm through condensate flow rate monitoring, and multiple protections are provided for the evaporator water level, temperature, pressure, etc. At the same time, strong corrosion-resistant devices are used to extend the service life of the instrument.

Kjeldahl nitrogen analyzer, with its intelligent operation, high-precision detection, data networking and other functions, has become an important instrument in the field of nitrogen content detection, providing a solid guarantee for quality control and scientific research in various industries.
