Scope

Main technical content: The specific surface area of solid materials has a significant impact on their adsorption performance, catalytic activity, and reaction rate, so it is necessary to conduct rigorous and accurate detection of the specific surface area of solid materials. Gas adsorption is a method used to detect the specific surface area of solid materials, and it is widely used in the characterization of powder materials and porous materials. It plays an important role in understanding and characterizing the physical and chemical properties of solid materials. The inter-laboratory comparison of specific surface area detection by gas physical adsorption instruments is an activity in which laboratories use such equipment to detect the specific surface area of solid materials. By comparing the differences between the detected values and the specified values, it can be determined whether the participating laboratories need to pay attention to the reasons causing these differences. Therefore, it is very important to select appropriate criteria for evaluating the results.
