Kjeldahl apparatus 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 the protein is constant. It is widely used to analyze the nitrogen content or protein content of food, crops, seeds, soil, fertilizer and other samples.

During the use of Kjeldahl nitrogen analyzer, some problems will inevitably occur. If not dealt with them in time, it will greatly affect the results of our use. For example: Why does the Kjeldahl nitrogen analyzer keep titrating? The main reasons are as follows:

1. It is because the solenoid valve of the Kjeldahl nitrogen analyzer is powered off and cannot be opened, and it requires to shut down the analyzer for repair.

2. The solenoid valve and pipeline are blocked. It is required to clear the solenoid valve and pipeline.

In the of use automatic Kjeldahl analyzer, we need to have a certain understanding of its daily maintenance. For example: when the instrument is used for a long time, the scale on the heater should be cleaned in time to ensure good heating efficiency. The distiller should be cleaned promptly when out of use. Only in this way can its service life be effectively extended and its performance fully utilized.
