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 Testing

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, ...

BET Surface Area analysis

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 ...

BET theory

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 ...

BET Theory

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

Determination of the specific surface area (BET surface area)

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 ...
