GB 608-88 Chemical Reagents-General Method for Nitrogen Determination
GB 608-88 Chemical Reagents-General Method for Nitrogen Determination is a standard that sets the methods and requirements for chemical reagents used in determination of nitrogen in a wide range of applications, including the determination of nitrogen in fertilization material, soil and wastewater.
The standard sets the requirements of the chemical reagents such as water quality, (purity of water, pH, nitrogen free sulfuric acid, nitric acid and formaldehyde), their chemical properties (appearance, solubility, total nitrogen content, unit of measurement and other technical indicators), purity and stability, among others. It also outlines the preparation procedure, storage and labeling methods.
The standard is extremely important, since it provides a common method for all the members of the chemical reagent industry, who use chemical reagents in the determination of nitrogen on a regular basis. Such industry includes fertilization material, wastewater and soil analysis laboratories, chemical companies, fertilizer production companies and environmental laboratories.
The standard helps ensure that all chemical reagents used by these members of the industry meet the specified requirements, ensuring accuracy and uniformity. This helps bring a higher degree of trustworthiness in chemical reagent products that support the nitrogen measurement process.
In addition, this standard ensures chemical reagents are being used in a consistent and uniform manner, reducing any sources of variability in chemical reagent usage. Using a unified method also helps to reduce labor costs, as well as time needed for the analysis, further enhancing the efficiency of chemical analysis techniques.
Finally, this standard helps chemical reagent manufacturers to produce quality products, as it outlines specific requirements and expectations for the chemical reagents. It helps manufacturing companies to design, develop and manufacture products with greater accuracy, resulting in higher reliability and fewer discrepancies in analytical data. As a consequence, the overall quality of analyses carried out with chemical reagents improves, resulting in greater accuracy and more reliable determinations of nitrogen.
