nitrogen determination

Nitrogen determination is a laboratory process used to measure the amount of nitrogen in a sample, such as food, soil, or biological material. This is important because nitrogen is fundamental to proteins and other biological molecules. The process typically involves converting all nitrogen compounds into a form called ammonia or nitrate, which can then be quantified using chemical reactions or instrumental techniques. Accurate nitrogen measurement helps assess nutritional value, soil fertility, or environmental pollution. Overall, it provides vital information about the composition and quality of a sample by focusing on its nitrogen content.
