Protein determination

The Kjeldahl method is a classical chemical method for determining nitrogen content in organic and inorganic substances. It is widely used for analyzing food products, animal feed, soil, water, and other materials. The results are typically used to calculate the protein content in a sample, as protein is composed of nitrogen.

Advantages of the Kjeldahl Method

  • High accuracy and reproducibility.
  • Suitable for a wide range of materials.
  • Universal application for both organic and inorganic compounds.

The Kjeldahl method remains one of the standard techniques for nitrogen and protein determination in chemical and food laboratories due to its reliability and versatility.
