Quantachrome announces that its popular NOVA series of rapid B.E.T surface area analyzers will be available in 2008 with an enhanced "calibration-free" analysis mode in addition to its already standard helium-free mode. This new versatility will make technology transfer easier in those industries where surface area measurement is a staple such as catalysts, chemicals, pharmaceutical & nanomaterials and where both techniques are commonly employed.
Quantachrome announces that its popular NOVA series of rapid B.E.T surface area and pore size analyzers will be available in 2008 with an enhanced "calibration-free" analysis option. The NOVA is one of Quantachrome's highly successful gas sorption instruments for characterizing powder and porous materials in terms of surface area and pore size & volume - essential in the pharmaceutical, petrochemical and advanced materials industries, to name but a few.
All new NOVA instruments will have the upgrade which allows the user to use not only its popular (& patented) helium-free, calibrated-cell-mode but also the classical, cell-calibration-free mode which does employ helium.
Why both methods? Dr Martin Thomas, Quantachrome's Business Development director explains: "At Quantachrome we focus not only on good science, but also on customer preferences - so we like our products to be as flexible as possible. Both methods are perfectly acceptable and in fact both are included in the recent ISO standard 15901-2: " Analysis of Mesopores and Macropores by Gas Adsorption " , so a user is free to select either one and remain on scientifically solid ground. But, for many customers standard operating procedures and analytical methods are written around just one method, not both... so it's important to have an instrument that can immediately take its place in their lab without having to rewrite associated documents. That logic similarly applies to technology transfer between R&D and quality control for example. And with many company mergers taking place, that clash of historical differences usually leads to a conflict in laboratory protocols... one company did it one way, the other did it another way. The NOVA can adapt to either so the company can adopt either, or the new merged company can continue to do analyses both ways on a single instrument if they wish. A different company might choose start off using the (historical as far as they are concerned) classical mode then switch to helium-free (on the same instrument) to reduce the number and types of gas cylinders in use. The NOVA continues to be a cutting-edge, adaptable instrument, just as it was when it was first introduced some fifteen years ago."
The new-for-2008 classical mode also eliminates the need to employ other adjustments for sample volume or density which most helium-free techniques require. The NOVA never requires "balance tubes" and is available in 1, 2, 3 or 4-sample variations.
Quantachrome Instruments, founded in 1968, is a world leader in the design and manufacture of analytical instrumentation for characterizing properties of porous materials and powders. Dedicated to providing the highest quality scientific instrumentation and support, Quantachrome has more than 50 sales, service and distribution offices worldwide. Quantachrome celebrates its 40th Anniversary in 2008.
B.E.T. (surface area) is named after the three scientists, Stephen Brunauer, Paul Emmett and Edward Teller, who in 1938 published the mathematical model which made surface area measurement by gas adsorption a viable technique, and which continues to be a fundamental part of porous materials characterization to this day. The B.E.T. equation celebrates its 70th Birthday in 2008.
