Micromeritics offers extended pore size analysis for ultramicropores down to 0.35 nm

November 11, 2020

Micromeritics Instrument Corporation, Norcross, Georgia, USA, a supplier of high-performance systems used to characterise particles, powders and porous materials, reports that its fully automated Micromeritics TriStar II Plus 3030 surface and porosity analyser enables users to combine the information gathered from nitrogen and carbon dioxide isotherms to deliver a full pore size distribution on materials such as carbon slit pores, where pores of molecular sizes are present.

The range of pore size analysis available in this method is extended to smaller pore sizes compared to the standard nitrogen analysis, explains the company. Using CO$_2$ provides access to ultramicropores that are not accessible to N2 at cryogenic temperatures due to kinetic size restrictions, connectivity problems, or extremely slow diffusion.

The TriStar II Plus 3030 uses an advanced non-local density functional theory (NLDFT) model, and, as a three-station unit, ensures a rapid and comprehensive material insight leading to speedy and efficient routine quality control analyses. In addition, the analyser has the accuracy, resolution and data reduction capability to serve research requirements.

The TriStar II Plus accommodates the use of nitrogen, argon, carbon dioxide, and other non-corrosive gases such as butane, methane, or light hydrocarbons. For applications including APIs, excipients, abrasives, and other low surface areas (< 1 m$^2$/g), a krypton option enhances the measurement precision for these materials that may be difficult to characterise. Micromeritics MicroActive data reduction and control software are said to provide a simple-to-use interface that rapidly transforms data to precise surface area and porosity information.

“The TriStar II Plus 3030 is a well-established surface area and porosity analyser that is highly appreciated by the academic and industrial market as it provides the utmost flexibility to our customers for a wide range of applications – from Additive Manufacturing, batteries and fuel cells to catalysts, nano tubes or pharmaceuticals,” stated Terry Kelly, president and CEO of Micromeritics. “Versatile analysis and data reduction underline our ongoing commitment to providing superior measurements and textural properties.”

Powder Metallurgy: The original net-shape production process

Powder Metallurgy components are relied upon by a wide variety of manufacturing industries, from automotive to power tools, household appliances, chemical engineering, filtration and more.

The main reason for the technology’s success is its cost-effectiveness at producing high volumes of net-shape components, combined with its ability to allow the manufacture of products that, because of the production processes, simply cannot be manufactured by other methods.

To discover more about how the technology has revolutionised component production, browse our Introduction to Powder Metallurgy.
