QUADRASORB evo Measure Surface Area and Pore Size

The QUADRASORB evo Gas Sorption Surface Area and Pore Size Analyzer allows users to run multiple independent samples synchronously at variable start times.

The flexible field upgrade paths provided by Anton Paar enable users to procure equipment depending on their current lab requirements, but with the flexibility of upgrading to micropore capability for low surface area analysis or upgrading analysis stations for optimized throughput at a future date.

Accurate B.E.T surface area measurements can be rapidly obtained with the standard evo™ version. High throughput industrial material characterization labs can analyze multiple samples at drastically improved speeds using the new B.E.T Quick Mode™.

Advanced material characterization can be performed with the micropore equipped version, which can measure extremely low surface area samples and microporous materials with the help of a 1torr low-pressure transducer and turbopump.

QUADRASORB evo Kr/MP for low surface area and micropore measurements features all of the functions of the standard model QUADRASORB evo in addition to low surface area measurement through Krypton adsorption or low-pressure micropore characterization.

It is equipped with low-pressure 1 torr transducersensors and an oil-free turbomolecular vacuum system. It carries out Krypton gas sorption measurements to determine the very low surface area of powdered metals and pharmaceutical actives.

It delivers low-pressure adsorption data (as low as 4 x 10-5 P/Po) crucial for the comprehensive characterization of microporous materials, including activated carbons, zeolites, and molecular sieves.

Key Features

The following are the key features of the new QUADRASORB evo Gas Sorption Surface Area and Pore Size Analyzer:

BET QuickMode for industrial high throughput settings, saving time by up to 50%

Bypasses most initialization, transducer zeroing sequences, and extended evacuation

Can synchronously run multiple samples

Can perform four sample runs within 25min

Dedicated Po transducer and manifold allows continuous sample dosing during measurements:

Po can be continually measured

Po can be updated without stopping the measurement

No slow down in analysis to measure Po

Flexible Po Modes

It is possible to estimate Po from ambient atmospheric pressure

It is possible to enter Po as a fixed value

It is possible to analytically measure Po

New Dose Wizard™ flexibility

Can use a previously measured sample as a dosing template for shortened analysis time

Can be used with or without QuickMode™

New hardware features

Integrated insulated dewar covers included in lift mechanism to increase the life and insulate the dewars content

Stainless steel gas paths including metal-metal seals for optimal vacuum performance

New 1torr low-pressure transducer for Krypton and micropore measurements

Soft closing protective door with pneumatic hinges for operator safety

Smooth belt drive dewar lift for precise control of Anton Paar’s novel cold zone

Key Benefits

The key benefits of the QUADRASORB evo Gas Sorption Surface Area and Pore Size Analyzer are listed below:

RTD sensors at each station ascertain automatic control of coolant at a level, ensuring minimum cold zone and maximum sensitivity

Automated, independent dewar elevators for each analysis station, plus self-adjusting dewar covers

Two measurement techniques are available as options: Patented NOVA® helium-free method or classical helium void volume method.

All stations can utilize 12mm, 9mm or 6mm glassware for maximum flexibility

Long-life dewar flasks for measurements lasting up to 30h with liquid nitrogen

Each of the four analysis ports includes separate and independent dewar (coolant flask) with Po (adsorbate saturated vapor pressure) measurement station, pressure transducer, and coolant level sensor for concurrent measurements yielding optimum flexibility and throughput

It is possible to independently program each analysis with different analyses and measurement conditions

Low maintenance, vacuum volumetric system with temperature monitored dosing manifold

Quadrawin™ software ver 3.0+ is capable of operating up to 3 QUADRASORB units simultaneously, from a single PC

Soft-close transparent blue cover gives protection to dewars and sample stations during analysis and allows users to access analysis stations easily as it opens vertically and automatically closes slowly

Stainless steel dosing and sample manifolds with metal-to-metal (VCR) seals

Communication port for PC control via Windows® based software

Multiple gas dosing methods to improve analysis time and resolution

Standard can modify dose pressure in accordance with sample demands intelligently

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

Delta (volume) Max™ includes data points in regions of large uptake and therefore no missing of pore filling step

Dose Wizard™ can be used with or without QuickMode™ enabled

This product is a former Quantachrome product. On February 9, 2018, Anton Paar acquired Quantachrome. Under the umbrella of the Anton Paar Group, the company will continue operations in Boynton Beach. Quantachrome is the first manufacturing facility in North America run by Anton Paar and will also function as a US-based unit for research, development, and production within the Anton Paar Group.
