Waters Sep-Pak Alumina N 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 50 - 300 µm, 20/pk

제품 설명

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.
