Autosorb-iQ is now available in MP-XR and C-XR models, which include a 0.1 torr transducer for extended-range low-pressure capability and extra resolution, suiting it to nanoporous materials research.
Quantachrome's Autosorb-iQ2 series of gas sorption analysers has dual sample capability, allowing it to analyse two microporous samples simultaneously.
The analysers also feature a coolant dewar, which can hold liquid nitrogen 90 or more hours; turbo-pumped sample preparation as standard on the MP version; software that can control up to four instruments; hybrid flow and static chemisorption on the C-TCD version; and many configurable options, including vapour-dosing capability.
This latest model extends the low pressure physisorption capability of MP and C versions by a factor of 10, down to the 10-8 relative pressure range for nitrogen adsorption at liquid nitrogen temperature, by incorporating a 0.1 torr pressure transducer in place of the standard 1 torr lowest range transducer.
The dual-sample iQ2 model is offered with dual 0.1 torr transducers, one for each sample manifold, to maintain its simultaneous measurement capability across all pressure ranges.
The 0.1 torr transducer is internally heated for improved stability and reproducibility.
The sensitivity and resolution of the new optional 0.1 torr transducer is ten times that of the standard 1 torr transducer at relative pressures below 1 x 10-4 P/Po.
This benefits, for example, those researchers working with specially synthesised nano- and microporous materials often only available in very small quantities.
The Autosorb-iQ's metal O-rings and metal gasket seals in critical measurements zones assure its ability to measure reproducibly in the extended low pressure range.
Upgrade kits are available to users of existing Autosorb-iQs.
