PRF - BET Surface Area Analysis

The term BET was derived from the first initials of Burnauer, Emmett and Teller, and refers to the method of measuring the surface area and porosity of solid materials using the principals of physical adsorption and de-sorption of gas. The Micrometric's ASAP 2010 system has the versatility to characterize samples using a number of different adsorptive gases such as: Nitrogen, krypton, oxygen, carbon dioxide, carbon monoxide, and butane. The system performs automatic single-point and multi-point BET surface area measurements, as well as Langmuir surface area, Olivier-Conklin DFT (tm) analyses, full adsorption and de-sorption isotherms, pore size distributions, and pore volume distributions.

The ASAP 2010 data acquisition system allows resolution of pores separated by only a fraction of an angstrom. The micro-pore system combines various techniques in one static-volumetric instrument such as: Harword-Kawazoe, Dubinin (both Astokhov and Radushkevich models), MP-Method, t-plot method, and Saito-Foley method. Sample tubes used in the system are available for various size pellets, cores and powders and pressure measurement range varies from 0 to 950 mmHg.
