GB/T 614-2021 《Chemical reagent—General method for the determination of refractive index》 Related products

GB/T 614-2021 stipulates a general method for the determination of Refractive index of chemical reagents. The standard describes the principle of Refractive index determination and clarifies the operation points of suitable instruments such as Abbe refractometer. From sample preparation, such as ensuring that there are no bubbles and impurities, to instrument calibrating, measurement process, and result calculation and data processing, it is explained in detail. Through unified and standardized operation, the Refractive index of chemical reagents can be accurately determined, providing reliable data support for chemical, pharmaceutical, scientific research and other industries in mass detection of reagents, formulation research and development, etc., to ensure the accuracy and Stability of chemical reagent applications.
