The Kjeldahl nitrogen analyzer is based on the Kjeldahl method, which indirectly calculates protein content by measuring the nitrogen content in a sample. The Kjeldahl nitrogen analyzer is easy to use and provides accurate measurements, but regular maintenance and upkeep are necessary.

How to extend the lifespan of nitrogen analyzer?

1. Because the instrument requires heating and distillation during operation, good ventilation and heat dissipation are essential.

2. Regularly clean and remove any sediment from the alkali solution and boric acid solution containers.

3. After the experiment, clean the instrument with steam.

4. After the experiment, wipe away any residual liquid from the distillation head and tube holder.

5. Inspect the distillation head. Replace it if there are cracks or deep scratches at the interface. Take care to protect the distillation tubes during replacement.

6. Inspect the digestion tubes for cracks and nicks along the edges, and for star-shaped cracks at the bottom. Replace the tube if any of these issues are found.
