N2 adsorption-desorption isotherm/ BET analysis

Model: Micrometric ASAP 2060 and BELSORP-max model

The N2 adsorption-desorption isotherm/BET analysis is a technique used to determine the surface area, porosity, and textural properties of materials, particularly porous substances such as catalysts and adsorbents. In the typical process, nitrogen gas is adsorbed onto a sample at a constant temperature, and the amount adsorbed is measured at varying pressures. Desorption is then carried out by reducing the pressure, and the resulting data forms an adsorption-desorption isotherm. This technique is also employed in the study of materials like zeolites, carbons, and polymers, which rely on high surface areas for optimal performance. Additionally, it is applied to evaluate the structural properties of materials used in filtration, gas storage, water adsorption, and environmental applications.
