Kjeldahl nitrogen analyzer, also known as nitrogen analyzer, protein analyzer, crude protein analyzer, is an instrument that uses the Kjeldahl nitrogen determination method to measure the nitrogen content in the sample and thus calculate the protein content.

Kjeldahl nitrogen analyzer uses the Kjeldahl method to detect ammonia, protein nitrogen content, volatile fatty acids and other contents in grains, food, feed, water, soil, sludge, sediment and chemicals. So, how to extend the service life of Kjeldahl nitrogen analyzer:

1. The equipment should be placed in a ventilated and dry environment with good heat dissipation.

2. If liquid accumulates in the container in front of the equipment, it should be cleaned frequently.

3. After long-term use, the heater will have scale, which needs to be cleaned regularly, otherwise it will affect the heating efficiency of the heater.

4. The alkali barrel and boric acid barrel should be cleaned regularly.

Kjeldahl apparatus has a very good cost-effectiveness. Only the titration process requires manual operation, which is very suitable for routine testing in laboratories and inspection agencies. It is widely used in the analysis of nitrogen content or protein content of samples such as food, crops, seeds, soil, fertilizers, etc.
