Specific Surface Area and Pore Size Analyzer

The specific surface area and pore size analyzer measures the specific surface area and pore size distribution of materials using the gas adsorption method. Solid samples adsorb gas molecules at low temperatures, and the specific surface area is calculated based on the adsorption amount, while the pore size is analyzed using the desorption curve. It is used for characterizing the properties of porous materials such as catalysts and adsorbents.
Selection
When selecting, consider the material's pore size range: microporous materials are suitable for the vacuum volumetric method, while mesoporous materials can be analyzed using the capacity method. Choose the analysis gas based on sample characteristics, typically using nitrogen for routine measurements and krypton for small specific surface areas. Pay attention to the instrument's detection limit and repeatability, ensuring precise temperature control. The supporting software should support mainstream analysis models.
