Gas sorption analyzer designed for flexibility, accuracy, and speed
QUADRASORB evo is a high-performance surface area and pore size analyzer with four 100 % independent analysis stations. Four simultaneous and independent analysis ports remove the limitations of single dewar systems allowing samples to be started as soon as previous measurements are completed. It is designed to meet the throughput needs of any R&D or QA laboratory wanting reliable and accurate BET surface area and detailed pore size results. Essentially four units in one, with an optional micropore or krypton version. A dedicated transducer has been provided for measurement of Po (adsorbate saturated vapor pressure), so that continually measuring Po does not slow down analysis capabilities. The new BET “QuickModeTM” provides high throughput industrial materials characterization labs the ability to process samples at dramatically improved speeds. QUADRASORB evo is the most cost-effective and flexible solution for busy labs.
Features & Benefits
BET QuickMode™ - For industrial high throughput settings - Time savings up to 50%.
• By passes most initialization, extended evacuation, and transducer zeroing sequences.
• Samples can run synchronously.
Dedicated Po transducer and manifold provides uninterrupted dosing of samples during measurements.
• Po can be continually measured.
• No need to stop measurement to update Po.
• No slow down in analysis to measure Po.
Flexible Po Modes
• Po can be estimated from ambient atmospheric pressure.
• Po can be entered as fixed value.
• Po can be analytically measured.
Hardware Features
• Soft closing protective door with pneumatic hinges for operator safety.
• Integrated, insulated dewar covers incorporated in lift mechanism to extend the life and
insulating the dewar content.
• Smooth belt drive dewar lift for precise control of Quantachrome’s novel small cold zone.
• 1 torr, low pressure transducer for krypton and micropore measurements.
• Stainless steel gas paths including metal to metal seals for optimal vacuum performance.
New Dose Wizard™ Flexibility
• Can use a previously measured sample as a dosing template for reduced analysis time.
• Can be used with or without QuickMode™.
