Micromeritics Instrument Corporation Particle Size Analysis, Porosity, Adsorption Surface Area

Micromeritics is a manufacturer and distributor of materials characterization analytical instrumentation for a broad range of research and quality assurance/control applications. These analyzers measure the physical properties of solids and powders to include particle size and count, particle shape, surface area, porosity (pore size and pore volume), material density (absolute, envelope, and bulk), water adsorption, and chemical adsorption (catalytic activity and temperature-programmed reactions).

Micromeritics has also formed Particulate Systems, an umbrella brand created to market an auxiliary selection of laboratory instruments that complement Micromeritics’ particle characterization instruments. This brand includes instruments that measure high-pressure adsorption isotherms, magnetic content, particle shape, water vapor, and vapor adsorption. Micromeritics also offers analytical (MAS) and pharmaceutical (MPS) contract services that include BET surface area, particle size (6 techniques), particle shape, mercury porosimetry, vapor sorption, surface energy, and many more. Methods development and validation services are also available.

Particle Size Analysis / Count Analysis

Since no single particle size measurement technique is ideal for all applications, Micromeritics offers a selection of particle size, particle count, and particle shape analysis techniques. Micromeritics’ new Saturn DigiSizer^®II high-resolution particle size analyzer measures particle size in a range of 0.04 to 2500 micrometers.

The Particle Insight^™particle size and shape analyzer offers up to 28 different shape parameters analyzed in real-time in either aqueous or organic solvent suspensions with a size range from 3 to 300 micrometers in its standard configuration.Micromeritics’ Elzone^™II 5390 uses the electrical sensing zone technique to determine the size, number, concentration, and mass of a broad range of substances.

Adsorption Surface Area and Porosity Analyzers

The company offers a wide range of gas sorption systems for surface area and porosity measurements. Micromeritics’ ASAP^™ 2020 surface area and porosity system is designed to provide high-quality surface area, porosity, and chemisorption data suitable for both research and quality control applications. The instrument can be configured for chemisorption, micropore, high-pressure adsorption, and vapor sorption evaluations, without increasing lab space.

The TriStar^®II 3020 is an adsorption surface area and porosity analyzer that offers automated, simultaneous, and independent analysis of up to three samples. Applicable for both research and quality control applications, the instrument has a dedicated saturation pressure port and offers a krypton option for low surface area measurements.The ASAP^™2420 accelerated surface area and porosimetry system is designed for high-performance/high sample throughput with six independently operated analysis ports and twelve independently operated sample preparation ports.

Micromeritics’ low cost Gemini^™ VII 2390 systems utilize a patented twin-tube design to produce precise, rapid, and repeatable porosity and surface area measurements. Ideal for teaching, research, and quality control environments, the Gemini VII permits a wide range of surface area measurements without requiring krypton or argon gases.

Porosimeters

The AutoPore^™IV porosimeter offers speed, accuracy, and a wide measurement range. The instrument uses mercury intrusion to calculate numerous sample properties such as pore size distributions, total pore volume, total pore surface area, median pore diameter, and sample densities (bulk and skeletal).

Density Pycnometers

Micromeritics AccuPyc^®II 1340 gas displacement pycnometry system are fully automatic analyzers that provide volume measurements and density calculations on a wide variety of powders, solids, and slurries having volumes from 0.01 to 350 cm³. For high throughput, an integrated control and analysis module can operate up to five additional external analysis modules.

The GeoPyc™ 1360 determines the envelope volume and density of monolithic samples as well as the bulk volume and density of powdered materials. Use of a quasi-fluid displacement medium composed of nonhazardous microspheres having a high degree of flowability eliminates the need for the use of oils, solvents, or mercury.

Working with ETH Zurich, Micromeritics will be holding a workshop on Advanced Porous Materials between the 22nd and 23rd of August in Zurich, Switzerland.
