Describe the microkjeldahal method for determination of nitrogen. How the nitrogen value is converted into protein
The Micro-Kjeldahl method is a widely used method for determining the nitrogen content in a sample. The method is based on the conversion of nitrogen to ammonia, which is then distilled and titrated. The Micro-Kjeldahl method is a critical tool in a variety of applications, including the analysis of food, soil, fertilizer, and water samples.
In the Micro-Kjeldahl method, a sample of the material to be analyzed is digested in a mixture of sulfuric and potassium sulfate. This digestion releases the nitrogen in the sample as ammonia. __________ ____ ____ __________ __________ ___ ______ ________ ___.
