BET Surface Area analysis

2022年8月28日 — In BET surface area analysis, nitrogen is usually used because of its availability in high purity and its strong interaction with most solids.

BET Specific Surface Area is the most widely recognized technique for determining the surface area of solids and powders. Samples are first prepared by drying, ...

The BET method uses a measurement of the physisorption of a gas to derive a value of “surface area” for a sample. The gas molecules can pass between particles ...

Specific surface area is a scale-dependent property, with no single true value of specific surface area definable, and thus quantities of specific surface area ...

The BET theory is used to measure the surface area of solid or porous materials. It gives important information on their physical structure.

By means of the BET equation the amount of adsorbed gas, which build up one monolayer on the surface, can be calculated from the measured isotherm. The amount ...
