Determination and Analysis of Total Nitrogen in Plant Samples
Nitrogen metabolism plays a leading role in plant metabolism. Organic nitrides in plant tissues include protein nitrogen and non-protein nitrogen. Non-protein nitrogen is mainly amino acids and amides, as well as a small number of inorganic nitrides, which are small molecules soluble in trichloroacetic acid (TCA) solution.

The content of nitrogen in plant tissue varies with the physiological status and environmental conditions of plants. Therefore, the determination of its content is of certain significance to study the law of nitrogen absorption, transport, and metabolism of plants, as well as to determine the quality and nutritional value of agricultural products. The determination of plant total nitrogen includes sample decomposition and quantitative, Lifeasible of nitrogen in the solution to be tested, combined with your sample situation and your project requirements to provide you with accurate and reliable plant total nitrogen determination data.

Dried plant tissue samples, > 2g The experimental samples will not be returned, please back them up by yourself. Before sampling, it is necessary to set up the control group and the experimental group, and each group is suggested to repeat more than 3 times. Quick-frozen preservation with liquid nitrogen can minimize the leakage time of plant samples at room temperature. There is no restriction on plant varieties. For varieties with special requirements or rare varieties, please contact our staff for more information. [Inquiry] |
