Frequently Asked Questions

What is the bet surface equation?

The BET equation strictly describes a linear plot of 1/[X(P0/P)-1] vs. P/P0 which for most solids, using nitrogen as the adsorbate, is restricted to a limited region of the adsorption isotherm, usually in the P/P0 range of 0.05 to 0.35.

What is surface area determination using BET method based on?

The BET Equation, 2.3. 2 , uses the information from the isotherm to determine the surface area of the sample, where X is the weight of nitrogen adsorbed at a given relative pressure (P/Po), Xm is monolayer capacity, which is the volume of gas adsorbed at standard temperature and pressure (STP), and C is constant.

How does BET method work?

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 and into all pores, cracks, and surface roughness, so that the measurement probes the full microscopic surface area of the sample.

What is the bet surface area measurement?

Brunauer-Emmett-Teller (BET) surface area analysis is the multi-point measurement of an analyte's specific surface area (m2/g) through gas adsorption analysis, where an inert gas such as nitrogen is continuously flowed over a solid sample, or the solid sample is suspended in a defined gaseous volume.

How to do bet analysis?

After the gaseous monolayer of molecules is created, the sample is placed into a non-nitrogen atmosphere and heated. This allows the release of the adsorbed nitrogen gas molecules from the surface of the sample. The released gas molecules can then be quantified and the surface area and porosity calculated.
