Surface area analyzer

Literature is available on the company's Windows-based external surface area analyzer (WESA). This product is said to provide several key benefits over existing techniques, such as no need for liquid nitrogen or extensive sample preparation. Also, the test is said to be much less costly and time-consuming. The envelope surface area method is a way to measure the surface area through pores of a sample using the flow rate through the sample at a given differential pressure. Envelope surface area analysis can be carried out quickly using compressed air, according to the literature.
