SURFACE AREA, MICROPORE AND MESOPORE SIZE BY GAS SORPTION

iQ

Advanced micropore size and chemisorption analyzer

A highly sophisticated gas sorption analyzer with up to three micropore analysis stations, and four dedicated built-in sample preparation (degas) ports. Metal organic frameworks (MOFs), activated carbons and zeolites - indeed any type of microporous solid - are analyzed with equal ease thanks to powerful Windows-based software, the most extensive suite of density functional theory (DFT) pore size calculations, and a wide range of sample cell types.


Metal-to-metal (VCR) fittings employed in the measurement manifold(s) for extremely low leak rate allow high quality micropore size measurements using 0.1 torr or 1 torr transducers. Each physisorption analysis station is served by its own dedicated measurement manifold and transducer set. A dedicated Po (saturation pressure) transducer, and a long life dewar (90+ hours, even with three samples) are all standard features.

 

One port is available as a chemisorption station for complete catalyst characterization, complete with a high temperature furnace coupled with fan-assisted cooling. This station retains physisorption capability (except C-AG-ND model). The chemisorption versions are also offered with optional flow-based measurement capabilities (TPR, TPO, TPD, pulse titration).

A vapor dosing option is available for both physisorption and chemisorption versions 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, and 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, and configurations make the Autosorb iQ the most advanced pore size analyzer of its type available today, with a single PC being able to control up to 4 Autosorb iQ units.

 

Accessories

Cryosync:Cryocooler Accessory

CryoSync:
Accessory cryostat capable of enabling 50+ hour sample analyses at temperatures in the range of 82 to 115K with ±0.005K accuracy. Ideal for performing the most scientifically reliable micropore-mesopore and hierarchical pore structure characterizations with argon gas at 87.3K, according to the latest IUPAC recommendations (Thommes et al., Pure Appl. Chem. 87(9-10), 1051-1069 (2015)), but using liquid nitrogen instead of liquid argon or more involved alternatives. more.

CryoCooler

CryoCooler:
Sub-ambient temperature physisorption measurements at temperatures other than those of liquefied gases (e.g., LN2, LAr) are important for studying gas storage and separation using structured porous materials. This powerful and precise thermostat enables isotherm measurements from 20K up to 320K without liquefied gases or additional heating devices.

Thermostatted Bath

Thermostatted Bath:
For measurements at, or around, room temperature (e.g., vapor sorption studies with vapor option, or CO2 at OoC) chiller / heater / circulators are available. more...

autosorb iQ_Calorimeter Interface

Calorimeter Interface:
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.

Mass Spectrometer

Mass Spectrometer:
The capability of the MP/XR "Chemi" models are greatly enhanced by the addition of a quadrupole mass spectrometer (QMS). This accessory is "close-coupled" and requires no additional bench-space, and is just as capable but much more cost-effective than a separate stand-alone QMS system.

These chemisorption models are available with or without BET/mesopore physisorption capability. Ideal when micropore size distributions aren't needed, or your lab already has sufficient physisorption capability. The physisorption-capable model includes four degassing stations and the option to add up to more physisorption stations.

These chemisorption models have the necessary additional features for characterizing catalysts using flow methods of preparation and static isotherm measurements, yet retain all of the physisorption abilities of the standard versions. A second and even a third physisorption station can be added.

and options...


The physisorption-only micropore model feature a high vacuum system and low pressure transducers for high-quality, detailed micropore studies. They are available with up to three micropore analysis stations. Each "MP" analysis station is equipped with its own dedicated set of pressure transducers: 1 torr, 10 torr, 1000 torr. It can be upgraded to the Chemi version.
