Fully Automatic Kjeldahl Nitrogen Determination Apparatus

The fully automatic Kjeldahl nitrogen analyzer converts organic nitrogen in samples into ammonium salts through sulfuric acid digestion, separates them via alkalization and distillation, absorbs with boric acid, and then determines the nitrogen content through titration. It is used for detecting protein content in fields such as food, feed, and chemical industry.
Selection
When selecting, consider matching the sample processing capacity with the distillation speed, check the airtightness of the boric acid absorption and titration system, confirm the completeness of safety protection devices, pay attention to reagent consumption costs, and ensure the operation interface is simple and user-friendly.
