Product Details
The principle of titration method for determining nitrogen content is to convert the nitrogen element in the sample into a quantitatively titratable form through chemical reactions, and then indirectly calculate the nitrogen content through acid-base titration.
Application scenarios
1. Fertilizer analysis: Determine the effective nitrogen content in urea, ammonium sulfate, compound fertilizers, etc., to guide precise fertilization.
2. Food and feed: Calculate crude protein content
3. Soil and environmental monitoring: determination of total nitrogen and alkaline nitrogen (including ammonium nitrogen and nitrate nitrogen) in soil, evaluation of fertility and pollution.
4. Drug quality control: determination of the content of nitrogen-containing drugs (such as urea and propafenone).
5. Industrial wastewater and chemical products: Analysis of nitrogen content in wastewater ammonia nitrogen and chemical intermediates (such as aniline).
