A Re-Examination of a Specific Surface Area Research Material



Dennis B. Minor


Specific surface area(SSA) analysis is one of the most common, quick, and inexpensive techniques used in analytical laboratories to characterize a variety of solid materials using a variety of gases. The technique is not labor intensive, can yield results in as little a five minutes, and is environmentally benign. Nitrogen is the most common of gases used and in the past four years several new instruments have been introduced by various instrument manufacturers to take advantage of the speed and low cost of this technique. The BET analytical technique is used to characterize zeolites, polymers, metals, ceramics, composites and bio-materials. Inexpensive modifications to this technique can yield detailed information on porosity, pore size distribution, surface chemisorption, density, and bio-activity/availability.
