QUADRASORB Sl - Four Station Surface Area and Pore Size Analyzer

The QUADRASORB SI is a high-quality, high-performance Surface Area and Pore Size Analyzer with four independent analysis stations to meet the throughput needs of any research or quality assurance laboratory.

	Transparent blue cover protects sample stations and Dewars during analysis operation.
	Opens vertically for easy access to analysis stations.
	Four sample stations with dedicated P₀ measurement at each station.
	Automated, independent Dewar elevators for each analysis station.
	Lower front panel opens to provide unrestricted access for dewar placement, maintenance and cleanup.
	RS232 port for PC control via Windows® based software.

The QUADRASORB-SI for standard applications using a variety of gasses

Fully automated, four-sample port analyzer for surface area, pore volume and pore size measurements.
High resolution adsorption and desorption isotherms to detect fine pore structure detail.
Each of the four analysis ports includes separate and independent Dewar (coolant flask), pressure sensor and P₀ (adsorbate saturated vapor pressure) measurement station for simultaneous measurements yielding maximum throughput and flexibility.
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, or no, delay to other samples already in progress.
Long life Dewar flasks for measurements at least 30 hours.
User can 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: 1. MaxiDose™ automatically adjusts dose size in response to sample demand; 2. Constant Dose volume (0.1 - 10 cc per data point); and 3. Delta Volume which adds data points in regions of large uptake so critical pore filling is never missed.
Low maintenance, vacuum volumetric system with temperature monitored dosing manifold.
Windows® based QUADRAWin software provides for instrument control and a comprehensive range of classical and modern models for reporting surface area and pore size.
Wide range of separately supplied sample preparation devices (Degassers) to meet the need of any laboratory.

QUADRASORB SI -KR/MP for low surface area and micropore measurement

All of the functions of the standard model QUADRASORB SI plus low surface area measurement via Krypton adsorption or low pressure micropore characterization.
Includes low pressure (10 torr) sensor and patented oil-free turbomolecular vacuum system.
Performs Krypton gas sorption measurements for very low surface area determination, eg. pharmaceutical actives, powdered metals, etc.
Provides low pressure adsorption data (as low as 4 x 10^-5P/P₀) necessary for more complete characterization of microporous materials, eg. zeolites, activated carbons, molecular sieves, etc.
