Micromeritics

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. The all-new, fully automated ASAP 2020 Accelerated Surface Area and Porosimetry System is an essential tool for providing surface area and porosity measurements for a broad range of applications such as pharmaceuticals, ceramics, carbons, catalysts, paint & coatings, propellants, electronics, cosmetics, and aerospace materials.

The Micromeritics Chemical adsorption (chemisorption) analysis techniques provide much of the information necessary to evaluate catalyst materials in the design and production phases, as well as after a period of use. Catalytic activity is evaluated by measuring the amounts and types of reactive gas adsorbed. This volume of gas, along with an understanding of the reaction stoichiometry, is used to calculate metal dispersion, active surface area, size of crystallites, and surface acidity.

The Micromeritics ASAP 2020 Accelerated Surface Area and Porosimetry System uses the volumetric gas sorption technique to obtain high-quality data for research and quality control applications. Designed to provide surface area, porosity, and chemisorption data to materials analysis laboratories with ever-expanding needs, the system contains a multitude of data reduction methods and can be readily upgraded to perform micropore and chemisorption analyses.

The AutoChem II is a fully automated chemisorption analyzer that can provide your laboratory with the ability to conduct a comprehensive array of highly precise studies of chemical adsorption and temperature-programmed reactions. With this single instrument, you can acquire valuable information about the physical properties of your catalyst, catalyst support, or other materials. It can determine catalytic properties such as percent of metal dispersion, active metal surface area, acid strength, surface acidity and distribution of strength of active sites, BET surface area, and more.

Mercury porosimetry is an extremely useful characterization technique for porous materials. Pores between about 500 µm and 35 nm can be investigated. It provides a wide range of information, e.g. the pore size distribution, the total pore volume or porosity, the skeletal and apparent density and the specific surface area of a sample.
