Sep-Pak Alumina N 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 50-300 µm Particle Size, 30/pk [WAT054575]
Sep-Pak Alumina N Vac cartridges contain a highly active grade of alumina with a neutral surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This neutral alumina is suitable for applications such as synthetic crude oil fractionation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
