Gas Adsorption

Surface area and porosity are two important physical properties that determine the quality and utility of many materials. Differences in the surface area and porosity of particles within a material can greatly influence its performance characteristics.

Accurate and precise surface area and pore size distribution information is essential for the determination of performance (and resulting profitability) in manufacturing and production environments. Micromeritics´ physisorption and chemisorption analyzers provide reliable surface area determinations for a wide variety of applications.

TriStar_II_3020_small The Tristar® II 3020 provides high-quality surface area and porosity measurements on solid materials by using the technique of gas adsorption. The TriStar II is a fully automated, three-station analyzer capable of increasing the speed and efficiency of quality control analyses, with the accuracy, resolution, and data reduction to meet most research requirements.This easy-to-operate, tabletop instrument is designed to analyze up to three samples simultaneously for optimum throughput. Its speed and accuracy make it an ideal instrument for a wide variety of applications that include pharmaceuticals, catalysts, carbon, cosmetics, paints, pigments, geoscience, fuel cells, high-tech ceramics and much more.


asap_2020_thumb The ASAP 2020 Accelerated Surface Area and Porosimetry Analyzer uses gas sorption techniques for research and quality control applications. Also available is the Chemical Adsorption ("Chemisorption") option, which uses the static volumetric technique to determine the percent metal dispersion, active metal surface area, size of active particles, and surface acidity of catalyst materials.

gemini_thumb The Micromeritics Gemini V Series of surface area analyzers rapidly and reliably produces accurate and repeatable surface area and porosity determinations of your sample material. It's simplicity of use and ruggedness has earned the Gemini its place in laboratories worldwide as an essential tool in both research and quality control environments.

flowsorb_3_thumb The FlowSorb III is an entry-level single-point and multipoint BET surface area instrument. The FlowSorb measures surface area using the flowing gas method, which involves the continuous flow of an adsorptive and inert gas mixture over the sample at atmospheric pressure. It is ruggedly constructed and ideal for demanding analytical environments.

smartprep The FlowPrep 060 applies both heat and a stream of inert gas to the sample. The heat causes contaminants to desorb from the surface and the stream of inert gas sweeps them out of the sample tube. It lets you choose the temperature, gas, and flow rate best suited for your sample material and application. Needle valves allow you to introduce the flowing gas slowly to prevent fluidization of samples.

vacprep The VacPrep 061 Degasser prepares samples for surface area and pore structure analysis. Like Micromeritics' FlowPrep Degasser, the VacPrep provides a simple, easy-to-use method of preparing samples using the flowing gas method. In addition, the VacPrep offers a vacuum mode which prepares samples by heating and evacuation. The VacPrep thus offers two methods for removing contaminants such as water vapor and adsorbed gases from samples to avoid interference with surface area measurements. The VacPrep features six degassing stations, and a choice of vacuum or gas flow preparation on each of the six stations. This combination allows you to choose the preparation method that is best suited to your material and application. With the VacPrep, contamination of sample during transfer from the degas-to-analysis process is minimized. This greatly enhances reliability of operation and increases precision of results. The VacPrep lets you choose the temperature and preparation technique best suited to your sample.

Micromeritics also provides a number of Surface Area Reference Materials for use in the above mentioned systems. Please contact us for more information on which reference materials best apply to your application and type of instrument.
