Kjeldahl nitrogen analyzer is an instrument that calculates the protein content by measuring the nitrogen content in the sample based on the principle that the nitrogen content in protein is constant. Because the method of measuring and calculating the protein content is called Kjeldahl nitrogen determination, it is called Kjeldahl nitrogen analyzer, also known as nitrogen analyzer, protein analyzer, crude protein analyzer.

How to clean the glass components of Kjeldahl apparatus:

Set up cleaning. At the end of use each day, the cleaning procedure should be performed to fully flush the system. The splash guard and condenser should be rinsed with water to remove residual substances. The service life of the glass components can be extended by regular cleaning. Although the cleaning method is preset, it can be modified and adjusted according to the size of the sample tube. For emptying the sample tube, it is recommended to add more than 200mL of water to 300mL sample tube and set the distillation to more than 300s.

Kjeldahl nitrogen analyzer is a basic instrument for determining the nitrogen content in a sample. It has the advantages of safety, accuracy, reliability, time-saving, labor-saving, and high degree of automation. It has a very wide range of applications and plays important roles in different industries.
