BET surface area testing principle is from 3 men names, Langmuir is from one. Usually BET surface area mean multi-layer adsorption, but Langmuir refers to monolayer adsorption. BET surface area principle reflects the real adsorption situation an process for most materials, so, be treated more important and trustable than Langmuir surface area. There area some analyzers( e.g. V-Sorb 2800S, V-Sorb 4800) can test both BET and Langmuir, also with pore size related, you can ask from them for a free test, because our insitutes got one already.

What is the difference of the surface area of a cylinder and a rectangular prism?
The surface area of a cylinder prism has round shape and the surface of a rectangular prism has a square shape.
What is the difference between surface area and total surface area?
Area is used to find the amount of square units insided of a 1- dimensional figure. The formula is: Length x Width= area Surface is quite different. Think of it this way. You have a cardboard box. If you cut each seam of the box and found the area of each section, added them together, you would have the surface area. The formula is: (Length x width x 2)+(width x height x 2)+(height x length x 2)= Surface area
What is the relationship between surface area and rate of evaporation?
Evaporation is a process that takes place at the surface of a liquid, therefore the rate of evaporation is directly related to the surface area. Twice as much surface area will give you twice as much evaporation.
Is the relationship between the area of a face of a cube and the surface area of the cube a linear relationship?
Yes, it is.
What is the relationship between surface area and dissolution rate?
In general, the dissolution rate is directly proportional to surface area. This is because the surface area tells you how much solute is exposed to the solvent. The greater the surface area, the more solute molecules that can bind to the solvent molecules, which means more dissolution.
Is irving langmuir poor or rich?
As we known, Ivring Langmuir is poor, but he paid great contribute to adsorption determination, especially the Langmuir surface area. By GOLD APP INSTRUMENTS.
What is the difference between the Freundlich BET and Langmuir adsorption isotherms?
The Freundlich isotherm describes multilayer adsorption onto a heterogeneous surface with non-specific interactions, while the Langmuir isotherm describes monolayer adsorption onto a homogeneous surface with specific interactions. Freundlich assumes a continuous distribution of energies for adsorption, whereas Langmuir assumes a finite number of identical sites for adsorption.
What is the difference between apparent surface area and accepted surface area?
manila
What is the relationship between the surface area of the skin amount and heat lost through the skin?
the difference between this is that surface area
What was Irving Langmuir's profession?
physical chemist, especially the research in specific surface area determination (GOLD APP INSTRUMENTS)
What is the difference between surface area and area?
Area is usually pertaining to the area of a 2d object but surface is 3d object
What is the difference between lateral area and surface area?
the formulas for lateral area dont include the figures bases. surface area does.
What is the difference between surface area and radius?
surface area is the area of a 3D object radius is half of the diameter of a circle
Difference between surface area and lateral area?
Lateral area excludes the areas of the top and bottom faces, which are included in the surface area.
What is the difference between the area of each face on a box added up and the surface area of a box?
The surface area of a box is the sum of the areas of the individual faces. If that's what you said, then there is no difference.
What is the difference between area of curved surface of cylinder and surface area of cylinder?
Curved surface area includes the area of the length of the cylinder only whereas surface area includes the two bases as well...
How do you calculate specific surface area?
there are many calculation methods for specific surface area (SSA), such as Langmuir surface area, contrast reference materials methods, single and multi-point BET surface area, STSA etc. Different methods have different calculation equation ways. Should be confirm which SSA parameters you want to get--GOLD APP INSTRUMENTS.
