Gas adsorption measurement

Gas adsorption measurement is a widely used method in surface technology that is used to characterize the specific surface area, pore structure and adsorption capacity of materials. This technique is based on the adsorption of gases on the surface of a solid and provides important information about the surface properties and porosity of materials.

In gas adsorption measurement, material samples are brought into contact with a specific gas, typically nitrogen or carbon dioxide. The gas adsorption on the surface of the material leads to a change in gas volume, which is measured with an instrument such as a gas adsorption meter.

By analyzing the adsorption behavior, various parameters of the surface can be quantified, including the specific surface area, pore size, pore distribution and surface energy. These parameters are crucial for the characterization of materials in various applications such as catalysis, adsorption, filtration and separation technology.

Gas adsorption measurement makes it possible to investigate the porosity and pore structure of materials on a microscopic and nanoscale level. This is particularly important for the development of porous materials such as zeolites, activated carbon, MOFs (metal-organic frameworks) and nanoporous surface coatings.

In research and development, gas adsorption measurement is often used to investigate the structure-property relationships of materials, identify new adsorbents and optimize the performance of materials in various applications.

Overall, gas adsorption measurement is a powerful and versatile method in surface engineering that provides important insights into the surface properties and porosity of materials, contributing to the development of advanced materials and technologies.
