Surface area analysis

Our QuantaChrome Autosorb iQ gas sorption analyser uses nitrogen gas to determine the total surface area per gram and porosity of your materials, 

When studying interactions at the surface, such as catalysis, it is often of paramount importance to understand how many sites you have on your material, to know what exactly the surface area is in a given amount. This key piece of information is what our Autosorb gas sorption analyser can tell you through the adsorption and desorption of nitrogen gas at 77 K. From the isotherms it obtains, total surface area per unit mass is calculated using the inbuilt BET method, given in m2/g. Not only that, if you have a porous material it can also tell you something about the nature of those pores, for example our instrument is particularly good at characterising micropores.

For more information or to discuss your surface area and porosity requirements, please contact our Dr Wayne Lam at wayne.lam@brunel.ac.uk
