Nitrogen analyzers are applied in many industries. Kjeldahl nitrogen analyzer is a classic method for measuring nitrogen in substances to convert crude protein. At present, Kjeldahl nitrogen determination method is generally used to determine the nitrogen-protein content of soil, food, agricultural products, feed and some substances. How to choose a nitrogen analyzer often troubles many users.

Tips for choosing nitrogen analyzer

I. Material

The nitrogen analyzer is an instrument that works in a harsh environment. Corrosive bodies such as concentrated sulfuric acid, boric acid, and sodium hydroxide and heating generate negative pressure in the instrument, which is a big test for the appearance of the instrument.

II. Condensing device

The effect of the condenser tube directly affects the recovery rate of distilled high-concentration samples, and a high-quality condenser tube can ensure that a sufficient amount of steam can be condensed to a sufficiently low temperature to ensure that the high-concentration sample does not leak, and the recovery rate of Kjeldahl apparatus is guaranteed.

III. Distiller

The main function of the distiller is distillation. It is an instrument for separating substances by distillation, which is very important in Kjeldahl nitrogen analyzer.
