BET Surface Area by Nitrogen and Krypton Adsorption The surface area of a material will often profoundly effect its behaviour and performance, whatever its application, and will commonly be a critical parameter to consider when preparing or procuring a material. Knowledge and control of surface area is often crucial at all stages of formulation, manufacture and ongoing QC processes.  Surface area, also termed Specific Surface Area (SSA), is most commonly measured by the BET (Brunauer-Emmett-Teller) method through the gas adsorption technique. For the majority of samples nitrogen adsorption is used, but for very low surface area materials a krypton adsorption option is also available. Key Information Surface area is a critical parameter for formulation, production and performance BET Surface Area by Nitrogen adsorption BET Surface area by Krypton adsorption for low area materials Comprehensive degassing options available to suit specific requirements Volumetric technique using state-of-the-art Micromeritics TriStar II 3020 Single point and multipoint measurement options available Flowing gas method available where required Argon adsorption option available Carbon dioxide adsorption available Sample degassing and drying immediately prior to analysis is critical to ensure that samples are clean and dry. This is undertaken by MCA and a range of options are available, including vacuum and flowing gas techniques at temperatures from ambient to 400 °C.   Nitrogen adsorption is applicable to the majority of sample types. However, as surface area becomes particularly low nitrogen fails to provide accurate data from which to calculate surface area. In such cases a krypton adsorption option is also offered which is capable of measuring the geometric area of essentially non-porous materials. Analyses are usually undertaken using the most recent Micromeritics TriStar 3020 instrument, offering a multipoint volumetric technique. However, a flowing gas technique and single point measurement options are also available which provide options to match historical methods and data.
