Kjeldahl Nitrogen Analyzer

The 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 the protein is constant. The Kjeldahl method’s universality, precision, and reproducibility have made it the internationally recognized method for estimating the protein content in foods and it is the standard method against which all other methods are judged. It is also used to assay soils, wastewater, fertilizers, and other materials.
