Introduction
GB/T 42307-2023 "Determination of Biuret Content in Urea-based Fertilizers by High Performance Liquid Chromatography" is a standard for the measurement of biuret content in urea-based fertilizers and soil conditioners.
Biuret is a compound that is formed during the production of urea and can have detrimental effects on crops if present in high concentrations. Therefore, it is crucial to accurately determine the biuret content in urea-based fertilizers to ensure their quality and effectiveness in promoting plant growth.
This standard specifies the high performance liquid chromatography (HPLC) method for the determination of biuret content in urea-based fertilizers. HPLC is a widely used analytical technique that offers high sensitivity and precision in separating and quantifying different compounds in a sample.
By following the procedures outlined in this standard, laboratories can accurately measure the biuret content in urea-based fertilizers, allowing manufacturers, farmers, and other stakeholders to ensure the quality and compliance of these products with regulatory requirements.
Overall, GB/T 42307-2023 provides a reliable and standardized method for the determination of biuret content in urea-based fertilizers, facilitating quality control and promoting the sustainable use of these products in agricultural practices.
