BET (Surface Area and Pore-Size Analyzer)

​A highly sophisticated gas sorption analyzer available with up to three physisorption analysis ports for surface area analysis and pore size measurements; any or all can be equipped for low pressure micropore analysis including 0.1 torr transducer(s).

Metal-to-metal (VCR) fittings employed in the measurement manifold(s) for extremely low leak rate, a dedicated Po (saturation pressure) transducer, and a long life dewar (90+ hours, even with three samples) are all standard features. 12mm, 9mm and 6mm sample cells (with or without bulbs) offer the widest sample-type flexibility.

One port is available as a chemisorption station, complete with a high temperature furnace coupled with fan-assisted cooling. The chemi- versions are also offered with optional flow-based measurement capabilities (TPX, pulse titration). The chemi station retains physisorption capability (except C-AGND model).

A vapor dosing option is available for both physi - and chemi-units and features a 50°C thermostatted manifold chamber.

All models (except one chemisorption-only model) include four built-in degas ports (turbo pumped vacuum is standard on the MP and XR models) and feature computer-controlled ramp/hold/test protocols, a dedicated cold-trap. This eliminates the need to degas on the analysis stations thus preventing contamination of the analysis section.

The host of models, options, accessories, configurations and upgrade-ability make the Autosorb iQ the most advanced instrument of its type available today, with a single PC being able to control up to 4 autosorb iQ units.
