Nitrogen content is a key indicator to distinguish protein from other organic compounds, so in order to determine the protein content, it is necessary to use precision instruments to measure the nitrogen content in the sample. Innova Kjeldahl nitrogen analyzer is a high-precision automated tool that can measure the nitrogen content in a sample and calculate the protein content using the principle of constant nitrogen content in protein.

How to determine protein content?

To determine the protein content, the organic compound sample containing protein is heated and digested with concentrated sulfuric acid and a catalyst in a test tube to decompose the protein. The ammonium ion produced combines with the sulfate ion to form ammonium sulfate. This compound then dissociates into ammonia gas through alkaline distillation, which is then absorbed by boric acid and titrated with a known concentration of hydrochloric acid titrant. The protein content is obtained by multiplying the consumption of acid by the conversion coefficient.

Based on the above methods, INOK1160 Automatic Kjeldahl Protein/Nitrogen Analyzer can provide users with intelligence, efficiency, energy saving, and data sharing solutions in nitrogen or protein determination of medic, agriculture, environmental monitoring， quality supervision, etc.
