Total Nitrogen determination in Urea – Dumas vs Kjeldahl Method
Urea is a crystalline substance widely used as a fertilizer, feed supplement, and starting material for plastics and drugs. It has a very high nitrogen content; it is readily converted to nitrate in the soil and is therefore considered one of the most concentrated nitrogenous fertilizers. The importance of having a controlled Nitrogen content in this product is crucial to always keep the same production standards.
