The QUADRASORB SI Surface Area and Pore Size Analyzer is a high-quality, high-performance Surface Area and Pore Size Analyzer with four independent analysis stations to meet the throughput needs of any process manufacturing research or quality assurance laboratory.
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 10-5 P/P0) necessary for more complete
characterization of microporous materials, eg. zeolites, activated carbons,
molecular sieves, etc.
