GB 10737-2007 《Working chemical - General rules for assay - Weight titration（potentiometric method）》 Related products

This standard specifies a general method for the determination of the content of working reference reagents using the weighing potential Titrimetric method. By accurately weighing the mass of the operating solution or reference solution and using the Potentiometric titration, pot-tiometry technique to determine the endpoint, the relative standard deviation of the determination results can reach 0.02%. This method is suitable for direct comparison between the reference material with similar chemical composition and the working reference reagent, ensuring the high-precision determination. The standard also specifies the preparation requirements and experimental conditions of the operating solution to ensure the accuracy and Reliability of the results. This method provides specifications and guidance for the high-precision determination of the content of working reference reagents.
