Surface Area & Pore Size Analyzer

2013 Quantachrome Corporation 13003 Rev. A -1013

Quantachrome’s QUADRASORB evoTM Surface Area and Pore Size Analyzer, is a four sample station, bench-top, fully automated, vacuum- volumetric gas sorption system. The QUADRASORB evoTM is a high-throughput, cost- effective system featuring four separate and independent measurement ports allowing for simultaneous analysis of four samples.

QUADRASORB evo™

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 .

Capable of running four (4) samples in as little as 25 minutes.

Dedicated Po transducer and manifold provides uninter-rupted 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.

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™

Proven Features:» Each analysis port can be independently programmed with different analyses and measurement conditions. New samples can be started on each port as prior measurements are completed with little delay to other samples already in progress.

» Choose from two measurement techniques:

• Patented NOVA® helium-free method and classical helium void-volume method.

» Multiple gas dosing methods to optimize analysis time and resolution:

• Standard™ -intelligently adjusts dose size in re-sponse to sample demand.

• Vector Dosing- user selectable dose volumes from 0.25 to 10cc per point

• Delta (volume) Max™ - adds data points in regions of large uptake so critical pore filling is never missed.

• Dose Wizard™ - can be used with or without Quick-ModeTM enabled. This allows the instrument to dose more aggressively, saving significant analysis time.
