Automatic selection of data points and optimization of BET surface area

The selection of data used for fitting BET surface area is often an easy process using the MicroActive software.  A broad range of isotherm data is selected and then the BET fit may be further refined to yield the specific surface area of a material.  The process for data selection and optimization has been fully automated using the BET surface area rules advocated by Professor Jean Rouquerol, CNRS Marseille, FR.  Prof. Rouquerol recommends the following criteria:

A simple method for combining pore size distributions calculated from gas adsorption isotherms with mercury intrusion porosimetry

MicroActive 2.0 and MicroActive for 3Flex include a powerful utility for including the pore size distribution from mercury porosimetry analyses with pore size distributions calculated from gas adsorption isotherms. This new import function allows users to rapidly view micro, meso, and macro pore size distributions in one easy to use application.
