Micro/Meso/Macro Pore Size Analysis by Gas Sorption, Mercury Porosimetry and Capillary Flow Porometry

Gas Sorption

Autosorb® iQ-XR

The gold-standard in micropore analyzers. Patented, dry high-vacuum system, ultra-stable transducers, three pressure ranges seamlessly overlap. Second and third, fully micropore enabled analysis stations are optional. Turbo-level degassing on four dedicated degassing ports perfectly complements low starting pressures for true micropore analysis. The desired protocol of heating rates, hold times and automatic testing are programmable. After completing the timed protocol, or sooner if residual pressure rise passes the user defined test limit, the iQ shuts down the degasser, backfilling the sample cell or leaving it under vacuum if preferred. This is also the model for very low surface area and thin film analyses using krypton gas. Additional options are available for specific applications -see chemisorption and more...

Quadrasorb-evo™

Up to 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. Krypton / Micropore option available for low surface area and micropore measurements. External roughing pump supplied separately. Secure PC version (21 CFR Part II) is also available. more...

Novatouch® Series

The next generation of well-established NOVA analyzers, offering higher speed and performance enhancements including a touch-sensitive, multi-functional color screen that provides reat time graphical and tabular displays of analyses, and enables local control in multiple languages and without a dedicated PC. Remote control via Ethernet connection, a dedicated Po cell, a longer life Dewar, and a novel and robust coolant level control system are provided. Standard and Advanced LX models are available with 1-to-4 analysis station versions, five input gas ports, and four built-in sample preparation ports with programmable heating profiles. Secure PC version (21 CFR Part II) is also available. more...

Nova®e Series

High-speed surface area and pore size analyzers for quality control and research. Meets different throughput needs with single or multi-port (two, three or four sample stations) models. Can be run as stand-alone or PC-based. Secure PC version (21 CFR Part II) is also available. Nova's small foorprint even includes built-in sample preparation stations! Operates in classical or helium-free mode. Vacuum pump supplied separately. more...

Novae Series

Autosorb®-6iSA

The new Autosorb-6iSA provides six ports for independent analysis of 1 to 6 samples. Dedicated pressure transducers, dewar flasks, coolant level sensors, and Po cells allow independent and simultaneous operation of each station. Its Windows®-based software, available as a 21 CFR Part 11 version, provides the ability to perform a multitude of data analysis methods including single and multi-point BET Langmuir surface area, mesopore volume and size distribution, micropore area, total pore volume and much more. Modern data communication provides ease of data input and export. more.

    Mercury Porosimetry

    PoreMaster® Series

    Automatic pore size distribution and pore volume analyzers using the rapid mercury intrusion method. Pore size range measured from approximately 1100* µm diameter to less than 3.5nm in the 60,000 psi capable units, 6.5nm in the 33,000 psi models. Both versions have two, built-in low pressure analysis ports for pore sizes above 4 µm. The high pressure cavity, for pore sizes smaller than 4 µm accommodates one sample cell in the standard unit, and two cells in the GT model for greater throughput. PoreMasters can also be used to determine the crush strength of hollow glass microspheres and for water intrusion studies on hydrophobic materials. more...

    Capillary Flow Porometry

    Porometer Series (Liquid Expulsion)

    Our capillary flow porometers for characerizing through-pores in thin, sheet-like materials provide exceptional performance in compact desk top units. They are ideal for material testing labs, research and development and quality control departments.All Porometer 3G Series capillary flow porometers conform to ASTM standard methods D6767, E128, F316-03, and similar and offer the benefits of the pressure sense line and a compact design with the sample holder options external to the control module. Having the sample holder external to the control module allows for measurement of a variety of sample configurations. more...
