This analyzer is unrivalled in catalyst characterization capability: one moment it's a rapid surface area and pore size analyzer, the next it is measuring active metal area and dispersion, even temperature programmed analyses. The mass spectrometer option is truly unique and remarkably cost-effective, it being close-coupled via a built-in vacuum chamber and gas sampling system. Note that the C (chemisorption) model retains all of the features of the MP (micropore) model - physisorption capability is never compromised because you need chemisorption data too.
