A major leap forward in gas sorption measurement technology
A highly sophisticated gas sorption analyzer available with one or two physisorption analysis ports for surface area analysis and pore size measurements, both of which can be equipped for low pressure micropore analysis including optional 0.1 torr transducer(s) (see XR models).
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 two samples) are all standard features. 12mm, 9mm and 6mm sample cells (with or without bulbs) offer the most sample-type flexibility.
One port is available as a chemisorption station, complete with high temperature furnace with fan-assisted cooling. The chemi- version is also offered with optional flow-based measurement capabilities (TPX, pulse titration). The chemi station retains full physisorption capability.
A vapor dosing option is available for both physi and chemi-units and features a 50oC thermostatted manifold chamber.
The two built-in degas stations (turbo pumped vacuum is standard on the MP and C models) feature computer-controlled ramp/hold/test protocols, a dedicated cold-trap, and optionally a second (dedicated) vacuum system. No need to degas on the analysis stations thus preventing contamination of the analysis section.
The host of models, options, accessories, configurations and upgradeability make the Autosorb-iQ the most advanced instrument of its type available today, and one PC can control up to 4 autosorb-iQ units.
Sub-ambient temperature physisorption measurements at temperatures other than those of liquefied gases (eg LN2, LAr) are important for studying gas storage and separation using structured porous materials. This powerful and precise thermostat affords isotherm measurements from 20K up to 320K without liquefied gases or additional heating device.
For measurements at, or around, room temperature (e.g. vapor sorption studies with Vapor option, or CO2 at OoC) chiller/heater/circulators are available.
Heats of adsorption are another important parameter associated with state-of-the-art applications using porous materials. These enthalpies can be measured calorimetrically using this accessory to interface the iQ to a third-party calorimeter.
The capability of the "Chemi" model is greatly enhanced by the addition of a quadrupole mass spectrometer (QMS). This accessory is "close-coupled" requiring no additional bench-space, and is just as capable but much more cost-effective than a separate stand-alone QMS system..
